These functions are only available under + Windows. + + - Colorbar function added. Thanks to Bruno Pincon. + + - Under Windows a toolbar has been added to the graphic windows, the + function toolbar can be used to set or unset it. + + +Numerical computation: +====================== + + - Sparse operations and functions like real, imag, matrix, spones revisited to + improve efficiency. Thanks to Bruno Pincon. + + - Bessel functions extended to work in the complex case (using Slatec routines) + Incompatibilities: The semantics of besseli, besselj, besselk and bessely + functions has been changed and extended. + The oldbesseli, oldbesselj, oldbesselk and oldbessely correspond to the old + obsolete semantics. + + - New version of linpro and quapro. Thanks to Cecilia Pola. + + - bvodeS function added to solve differential equation with boundary value. + Thanks to Rainer Von Seggern. + + - detrend function added to remove constant, linear or piecewise linear trend + from a vector. Thanks to Bruno Pincon. + + - Interface with Excel (Functions to read Excel files). + + + +Matlab to Scilab converter: +=========================== + + - translatepaths function improved to allow conversion on an entire toolbox + agating inference throught toolbox functions. + + - The set of translated function has been extented in particular with the + basic graphic functions. + + - Scilab function sum, prod,... extented to the "first non singleton" matlab + semantics to improve readability and efficiency of translated code. + + - Try catch construct added to Scilab for a better translation. + + +Scipad editor: +============== + + - A debugging tool is now available. + + - Drag'n'drop is now supported. + + - Split a Scipad window. + + - Print file from Scipad is now available. + + - Scipad is easily localized (See "Adding translations..." in the Scipad Help + Menu). Today English, German, French, Swedish, Polish, Norwegian and Italian + languages are supported. + + - User settings and text colors are now configurable and save across editing + sessions. + + - Colorization of strings rewritten - now supports strings on continued lines. + + - Colorization of files launched in the background, with progressbar. + + - Miscellaneous file management improvements: readonly flag, + absolute pathnames to files, pruned pathnames display, revert to + saved feature, MRU (Most Recently Used) list. + + - Quick access in the file menu for recently opened/saved files. + + - Identification of Scilab predefined variables and library functions in + scilab scripts. + + - Keyword completion added, keyword list now completely dynamical. + + - Undo/Redo rewritten. + + - Go to... functions rewritten and expanded. + + - Find/Replace rewritten, includes find files, find in files, find in multiple + buffers, find in selection only, find full word. + + - Creation of XML help page templates and xmltohtml compilation available from + within Scipad. + +Syntax: +======= + + - try-catch instruction added to improve programming with error control. + + +Other Improvements: +=================== + + - Configure adapted to linux 64bit architectures. + + - Use tcltk 8.4.12 - TCL interface has been totally rewritten (for better + error detection and better data transfert). ScilabEval improve to handle + synchronism. + + - Memory improvements under Windows platforms (particularly the management + of virtual memory or swap file). + + - Exception management added under Windows version. + + - Windows platforms with: + + Intel C Compiler 9.0. + + Intel Fortran 9.0. + + - The source files have been updated to optimise the compiled version built + with VC6 tool. Please note that the Windows binary version provided on + our Web site is built with .NET + + - Improvement of the integration of Visual Studio Compiler to the dynamic + links: findmsvccompiler() and configure_msvc() macros have been added. + + - Integration of the ATLAS library (specific Windows version). + During the installation of Scilab, dynamic library (Atlas.dll) is + automatically chosen according to the CPU detected. + See details in the Atlas.spec file under scilab\bin directory. + + Scilab can be used with Atlas library on all platforms by: + + + downloading Atlas library sources. + + compiling Atlas sources. + + compiling scilab sources with the following configure option : + --with-atlas-library=ATLAS_LIB_DIRECTORY + + (see <SCI>/configure --help). + + - Java interface written to allow calling Scilab computational engine from Java. + + - Font rotation is now possible under Xwindow. + + - SCI and HOME are redefined if not correct ( Bug 1488 Only for Windows ). + + - HOME variable (%HOME%) defined under Windows: c:/Documents and Setting/USER. + + - New environment variable SCIHOME: + + Under Windows: %HOME%\scilab\SCILAB_VERSION + + Under Linux: $HOME/USER/.scilab/SCILAB_VERSION + + - Function what() has been rewritten : alphabetical sort, print modified. + + - mkdir, rmdir, copyfile, toprint functions added for handling files and + directories from Scilab. + + - getshortpathname, getlongpathname, winqueryreg (Registers), console, + mcisendstring (MCI device), clipboard, functions added for a better + interaction with Windows environment. + + - getos, setenv, getmemory, sleep, functions added for a better interaction + with the operating system (Unix and Windows). + + - The perl function as been added to allow execution of Perl scripts from + Scilab. + + - The calendar function has been added. + + +New primitives: +=============== + + - clipboard (specific Windows) + - perl + - calendar + - mkdir + - rmdir + - copyfile + - sleep + - getos + - setenv + - toprint("file") + - getmemory() + - getshortpathname (specific Windows) + - getlongpathname (specific Windows) + - toolbar (specific Windows) + - hidetoolbar (specific Windows) + - console (specific Windows) + - mcisendstring (specific Windows) + - banner + - winqueryreg (specific Windows) + - xls_open + - xls_read + - scicos_debug_count + + +Please note: +============ + + - "xgetmouse", "eventhandler" event set extended to click, double-click, <Ctrl> Key. + See more details in xclick and xgetmouse on line help. + Warning: Because of distinction of click events, some users' scripts can + have a different behavior. + To make it work as before please check and modified test on events as follow: + supposing that button contains the value returned by xclick (left most argument) + or xgetmouse (third componant of returned vector) then replace test like: + button==0 by or(button==[0,3]) + button==1 by or(button==[1,4]) + button==2 by or(button==[2,5]) + + |
