/*
** Type definition
*/
We define types that way (but it can evolve in the future) :
I - Scalar
-----------
I.1 - Real
I.1.1 - Simple precision (float)
I.1.2 - Double precision (double)
I.2 - Complex
I.2.1 - Simple precision (float)
I.2.2 - Double precision (double)
I.3 - Integer (NOT IMPLEMENTED YET)
I.4 - Boolean (NOT IMPLEMENTED YET)
II - Matrix
------------
!! WARNING !!
Matrix are stored column ways.
Ex :
double M[4] = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0}
- If M has 2 lines and 3 columns :
M = [ 1.0 3.0 5.0 ]
[ 2.0 4.0 6.0 ]
- If M has 3 lines and 2 columns :
M = [ 1.0 4.0 ]
[ 2.0 5.0 ]
[ 3.0 6.0 ]
I.1 - Real
I.1.1 - Simple precision (float)
I.1.2 - Double precision (double)
I.2 - Complex
I.2.1 - Simple precision (float)
I.2.2 - Double precision (double)
I.3 - Integer (NOT IMPLEMENTED YET)
I.4 - Boolean (NOT IMPLEMENTED YET)
/*
** Functions Naming style
*/
We define this coding style for functions names :
<precision><function_name><variable_type>.
variable_type :
- 's' : Scalar
- 'a' : Matrix
precision :
- 's' : Real simple precision (float)
- 'd' : Real double precision (double)
- 'c' : Complex simple precision (float)
- 'z' : Complex double precision (double)
/*
** Transtyping functions
** FIXME : Add it into the users limitations.
*/
- acos(x) : Real input.
Return a Real value if x E [ -1 ; 1 ].
Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [.
- acosh(x) : Real input.
Return a Real value if x E ] 1 ; +inf [.
Return a Complex value if x E ] -inf ; 1 ].
- asin(x) : Real input.
Return a Real value if x E [ -1 ; 1 ].
Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [.
- atanh(x) : Real input.
Return a Real value if x E ] -1 ; 1[.
Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [.
- log(x) : Real input.
Return a Real value if x E ] 0 ; +inf [
Return a Complex value if x E ] -inf ; 0 [
- log10(x) : Real input.
Return a Real value if x E ] 0 ; +inf [
Return a Complex value if x E ] -inf ; 0 [
- chol(A) : Complex input
The diagonal must be real;
