+\section{Introduction}
+
+SciPy is open-source software for mathematics, science, and
+engineering.
+
+SciPy (pronounced ``Sigh Pie'') is a collection of mathematical
+algorithms and convenience functions built on the Numpy extension for
+Python. It adds significant power to the interactive Python session by
+exposing the user to high-level commands and classes for the
+manipulation and visualization of data. With SciPy, an interactive
+Python session becomes a data-processing and system-prototyping
+environment rivaling sytems such as \emph{Matlab, IDL, Octave, R-Lab,
+  and Scilab}. \cite{scipy}

+\section{A Glimpse of Scipy functions}
+
+This section gives a brief overview of the tasks that are going to be
+performed using Scipy, in future classes of this course.
+
+\subsection{Matrix Operations}
+
+Let $\mathbf{A}$ be the matrix 
+\(
+\begin{bmatrix}
+1 &3 &5\\
+2 &5 &1\\
+2 &3 &8
+\end{bmatrix}
+\) 
+
+To input $\mathbf{A}$ matrix into python, we do the following in
+\texttt{ipython}\footnote{\texttt{ipython} must be started with
+  \texttt{-pylab} flag}\\
+
+\begin{lstlisting}
+  In []: A = array([[1,3,5],[2,5,1],[2,3,8]])
+\end{lstlisting}
+
+\subsubsection{Inverse}
+
+The inverse of a matrix $\mathbf{A}$ is the matrix $\mathbf{B}$ such
+that $\mathbf{A}\mathbf{B} = \mathbf{I}$ where $\mathbf{I}$ is the
+identity matrix consisting of ones down the main diagonal. Usually
+$\mathbf{B}$ is denoted $\mathbf{B} = \mathbf{A}^{-1}$ . In SciPy, the
+matrix inverse of matrix $\mathbf{A}$ is obtained using
+
+\lstinline+inv(A)+.
+\begin{lstlisting}
+  In []: inv(A)
+  Out[]: 
+  array([[-1.48,  0.36,  0.88],
+         [ 0.56,  0.08, -0.36],
+         [ 0.16, -0.12,  0.04]])
+\end{lstlisting}
+
+\subsubsection{Determinant}
+
+The determinant of a square matrix $\mathbf{A}$ is denoted
+$\left|\mathbf{A}\right|$. Suppose $a_{ij}$ are the elements of the
+matrix $\mathbf{A}$ and let
+$\mathbf{M}_{ij}=\left|\mathbf{A}_{ij}\right|$ be the determinant of
+the matrix left by removing the $i^{th}$ row and $j^{th}$ column from
+$\mathbf{A}$. Then for any row $i$
+
+    \[ \left|\mathbf{A}\right|=\sum_{j}\left(-1\right)^{i+j}a_{ij}\mathbf{M}_{ij} \]
+
+This is a recursive way to define the determinant where the base case
+is defined by accepting that the determinant of a $1\times1$ matrix is
+the only matrix element. In SciPy the determinant can be calculated
+with $det$ . For example, the determinant of
+
+    \[ \mathbf{A}=\begin{bmatrix} 1 & 3 & 5\\ 2 & 5 & 1\\ 2 & 3 & 8\end{bmatrix}\]
+
+is
+
+    \begin{eqnarray*} 
+      |\mathbf{A}| & = & 1\begin{vmatrix} 5 & 1\\ 3 & 8\end{vmatrix}
+                        -3\begin{vmatrix} 2 & 1\\ 2 & 8\end{vmatrix}
+                        +5\begin{vmatrix}2 & 5\\ 2 & 3\end{vmatrix}\\  
+                   & = & 1(5\cdot8-3\cdot1)-3(2\cdot8-2\cdot1)+5(2\cdot3-2\cdot5)=-25
+    \end{eqnarray*}
+
+In SciPy, this is computed as shown below
+
+\begin{lstlisting}
+  In []: A = array([[1, 3, 5], [2, 5, 1], [2, 3, 8]])
+  In []: det(A)
+  Out[]: -25.0
+\end{lstlisting}
+
+\subsection{Solving Equations}
+
+\subsubsection{Linear Equations}
+
+Solving linear systems of equations is straightforward using the scipy
+command \lstinline+solve+. This command expects an input matrix and a
+right-hand-side vector. The solution vector is then computed. An
+option for entering a symmetrix matrix is offered which can speed up
+the processing when applicable.  As an example, suppose it is desired
+to solve the following simultaneous equations:
+
+    \begin{eqnarray} x+3y+5z & = & 10\\ 2x+5y+z & = & 8\\ 2x+3y+8z & = & 3\end{eqnarray}
+
+We could find the solution vector using a matrix inverse:
+
+    \[ \left[\begin{array}{c} x\\ y\\ z\end{array}\right]=\left[\begin{array}{ccc} 1 & 3 & 5\\ 2 & 5 & 1\\ 2 & 3 & 8\end{array}\right]^{-1}\left[\begin{array}{c} 10\\ 8\\ 3\end{array}\right]=\frac{1}{25}\left[\begin{array}{c} -232\\ 129\\ 19\end{array}\right]=\left[\begin{array}{c} -9.28\\ 5.16\\ 0.76\end{array}\right] \]
+
+However, it is better to use the solve command which can be faster and
+more numerically stable. In this case it however gives the same
+answer.
+
+\begin{lstlisting}
+  In []: A = array([[1, 3, 5], [2, 5, 1], [2, 3, 8]])
+  In []: b = array([[10], [8], [3]])
+  In []: dot(inv(A), b)
+  Out[]: 
+  array([[-9.28],
+         [ 5.16],
+         [ 0.76]])
+
+  In []: solve(A,b)
+  Out[]: 
+  array([[-9.28],
+         [ 5.16],
+         [ 0.76]])
+\end{lstlisting}
+
+\subsubsection{Polynomials}
+
+Solving a polynomial is straightforward in scipy using the
+\lstinline+roots+ command. It expects the coefficients of the
+polynomial in their decreasing order. For example, let's find the
+roots of $x^3 - 2x^2 - \frac{1}{2}x + 1$ are $2$, $\sqrt{2}$ and
+$-\sqrt{2}$. This is easy to see.
+
+\begin{align*}
+x^3 - 2x^2 - \frac{1}{2}x + 1 = 0\\
+x^2(x-2) - \frac{1}{2}(x-2) = 0\\
+(x-2)(x^2 - \frac{1}{2}) = 0\\
+(x-2)(x - \frac{1}{\sqrt{2}})(x + \frac{1}{\sqrt{2}}) = 0
+\end{align*}
+
+We do it in scipy as shown below:
+\begin{lstlisting}
+  In []: coeff = array([1, -2, -2, 4])
+  In []: roots(coeff)
+\end{lstlisting}
+
+\subsubsection{Non-linear Equations}
+
+To find a root of a set of non-linear equations, the command
+\lstinline+fsolve+ is needed. For example, the following example finds
+the roots of the single-variable transcendental equation
+
+    \[ x+2\cos\left(x\right)=0,\]
+
+and the set of non-linear equations
+
+    \begin{align} 
+      x_{0}\cos\left(x_{1}\right) &= 4,\\ 
+      x_{0}x_{1}-x_{1} &= 5
+    \end{align}
+
+The results are $x=-1.0299$ and $x_{0}=6.5041,\, x_{1}=0.9084$ .
+
+\begin{lstlisting}
+In []: def func(x):
+   ...:     return x + 2*cos(x)
+
+In []: def func2(x):
+  ...:     out = [x[0]*cos(x[1]) - 4]
+  ...:     out.append(x[1]*x[0] - x[1] - 5)
+  ...:     return out
+
+In []: from scipy.optimize import fsolve
+In []: x0 = fsolve(func, 0.3)
+In []: print x0
+-1.02986652932
+
+In []: x02 = fsolve(func2, [1, 1])
+In []: print x02
+[ 6.50409711  0.90841421]
+\end{lstlisting}
+
+\subsection{Integration}
+% To be done in the lab. 
+\subsubsection{Quadrature}
+
+The function \texttt{quad} is provided to integrate a function of one
+variable between two points. The points can be $\pm\infty$ ($\pm$
+\texttt{inf}) to indicate infinite limits. For example, suppose you
+wish to integrate the expression $e^{\sin(x)}$ in the interval
+$[0,2\pi]$, i.e. $\int_0^{2\pi}e^{\sin(x)}dx$, it could be computed
+using
+
+\begin{lstlisting}
+In []: def func(x):
+   ...:     return exp(sin(x))
+
+In []: from scipy.integrate import quad
+In []: result = quad(func, 0, 2*pi)
+In []: print result
+(7.9549265210128457, 4.0521874164521979e-10)
+\end{lstlisting}
+
+\subsubsection{ODE}
+
+We wish to solve an (a system of) Ordinary Differential Equation. For
+this purpose, we shall use \lstinline{odeint}. As an illustration, let
+us solve the ODE 
+
+\begin{align} 
+  \frac{dy}{dt} = ky(L-y)\\ 
+  L = 25000,\,k = 0.00003,\,y(0) = 250 \nonumber 
+\end{align}
+
+We solve it in scipy as shown below. 
+
+\begin{lstlisting}
+In []: from scipy.integrate import odeint
+In []: def f(y, t):
+  ...:     k, L = 0.00003, 25000
+  ...:     return k*y*(L-y)
+  ...:
+In []: t = linspace(0, 12, 60)
+In []: y0 = 250
+In []: y = odeint(f, y0, t)
+\end{lstlisting}
+
+Note: To solve a system of ODEs, we need to change the function to
+return the right hand side of all the equations and the system and the
+pass the required number of initial conditions to the
+\lstinline{odeint} function.

+The following piece of code, produces the plot in Figure \ref{fig:sin}
+using \texttt{pylab}\cite{pylab} in \texttt{ipython}\footnote{start
+  \texttt{ipython} with \texttt{-pylab} flag}\cite{ipy}
+

+In []: plot(x, sin(x))

+  \begin{itemize}
+  \item {\LaTeX} is a document based mark-up
+  \item Mark-up --- a system of annotating text, adding extra
+    information to specify structure and presentation of text
+  \item Document based markup $\rightarrow$ you don't have to worry

+BibTeX
+~~~~~~
+
+The previous section explained the process of listing references at the end of a document and embedding cross references. In this section let us explore the BibTeX environment for keeping track of references.
+
+Using BibTeX is a very convenient method to use, when writing multiple documents in a single area or field. BibTeX allows you to create a database of all your references and use them as and when required. 
+
+The BibTeX database is stored in a ``.bib`` file. The structure of the file is quite simple and an example is shown below. 
+::
+
+  @book{Lamport94,
+  author    = "Leslie Lamport",
+  title     = "A Document Preparation System: User's Guide and Reference",
+  publisher = "Addison-Wesley Professional",
+  year      = "1994",
+  edition    = "second",
+  note      = "illustrations by Duane Bibby"
+  }
+
+Each bibliography entry starts with a declaration of the type of the reference being mentioned. The reference is in the above example is of the book type. BibTeX has a wide range of reference types, for example, ``article, book, conference, manual, proceedings, unpublished``.
+
+The type of reference is followed by a left curly brace, and immediately followed by the citation key. The citation key, ``Lamport94`` in the example above is used to cite this reference using the command ``\cite{Lamport94}``. 
+
+This is followed by the relevant fields and their values, listed one by one. Each entry must be followed by a comma to delimit one field from the other. 
+
+To get your LaTeX document to use the bibliography database, you just add the following lines to your LaTeX document. 
+::
+
+  \bibliographystyle{plain}
+  \bibliography{LaTeX}
+
+Bibliography styles are files that tell BibTeX how to format the information stored in the ``.bib`` database file. The style file for this example is ``plain.bst``. Note that you do not need to add the ``.bst`` extension to the filename.  If you wish to achieve a particular style of listing the bibliography items and citing them, you should use an appropriate style file. 
+
+The ``bibliography`` command specifies the file that should be used as the database for references. The file used in this example is ``LaTeX.bib``

+\begin{document}
+Python is a general-purpose high-level programming language whose
+design philosophy emphasizes code readability. Python aims to combine
+"remarkable power with very clear syntax", and its standard library is
+large and comprehensive. Its use of indentation for block delimiters
+is unusual among popular programming languages.
+
+Python supports multiple programming paradigms, primarily but not
+limited to object oriented, imperative and, to a lesser extent,
+functional programming styles. It features a fully dynamic type system
+and automatic memory management, similar to that of Scheme, Ruby,
+Perl, and Tcl. Like other dynamic languages, Python is often used as a
+scripting language, but is also used in a wide range of non-scripting
+contexts. 
+
+The reference implementation of Python (CPython) is free and open
+source software and has a community-based development model, as do all
+or nearly all of its alternative implementations. CPython is managed
+by the non-profit Python Software Foundation.
