Many thanks to Scilab's developers for their invaluable support. Many thanks to Scilab's users for their encouragement.
Next to the on line help of the software, we advise you, to make the first move with Scilab,
to consult the Scilab step-to-step web site.
Scilab team express one's thanks to Jacques-Deric Rouault.
Please note that:
Scilab 4.x versions family will be the last versions working with the old graphics mode.
Scilab v 4.0 is the last release working with Microsoft Windows 98 and Microsoft Visual 6.0
(compilation, not incremental link) supported by Scilab operational team.
Scilab binary versions are built:
for Linux: gcc-3.4.3 and g77 compilers with a platform under Mandriva 2005.
No need to recompile except to use incremental link, we advise indeed to download
the source files if you are using others compilers.
for Windows: Visual Studio .Net 2003 and Fortran and C Intel compilers with a
platform under Windows XP Service Pack 2.
Recall: No Scilab GTK version is provided and supported by the operational team. Same way about MinGW and Cygwin.
Be sure that:
you have read/write rights on the directory where you want to install Scilab.
Plotframe syntax has been extended for optionnal argument (<optional_args>)
Maximal length of figure names has been increased
Graphical entities (objects) have been extended with a particular effort on:
The Axes entity with respect to change of coordinates (logscale enable, axes inversion in 2D and 3D) and graduation display.
Versatile Title and labels entities in 2D and 3D
3D object merge and zoom
Rotation of text entities
Save and load of all graphical entities
New functions have been defined to mimic their Matlab equivalent:
plot
surf
mesh
bar, barh and barhomogenize
pie
Graphical Environment improved and extended:
Manipulation of the hierachy of the entities has been made easier thanks to a hierachy browser.
A toolbar has been added to the graphic windows, the function toolbar can be used to set or unset it. (Windows specific)
Graphic window Events (mouse, keyboard,...) handling have been improved and extended:
Click, double_click, press, release ,move
Key press and release, with or without Shift and Ctrl modifiers.
xs2bmp and xs2emf functions added to export graphics under bmp and EMF (Enhanced Meta File) formats. (Windows specific)
colorbar function added
Numerical computation:
Sparse operations and functions like real, imag, matrix, spones revisited to improve efficiency
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
Interface with Excel (Functions to read Excel files).
Matlab to Scilab converter:
Translatepaths function improved to allow conversion on an entire toolbox propagating 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 saved across editing sessions
Colorization of strings rewritten - now supports strings on continued lines
Colorization of files launched in the background, with progressbar.
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 8.4.13 - 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 9.1
Intel Fortran 9.1
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
For advanced users: 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 /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
add scilex -nogui mode no window, no interactive, no gui, no events.
%gui variable in scilab to detect this mode.
Add 2 keys in registry to detect scilab (Windows):
On Windows XP 32 bits
[HKEY_LOCAL_MACHINE\SOFTWARE\Scilab] "LASTINSTALL"="Scilab-4.1"
[HKEY_LOCAL_MACHINE\SOFTWARE\Scilab\Scilab-4.1] "SCIPATH"="\"C:\\Program Files\\scilab-4.1\""
On Windows XP 64 bits
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Scilab] "LASTINSTALL"="Scilab-4.1"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Scilab\Scilab-4.1] "SCIPATH"="\"C:\\Program Files (x86)\\scilab-4.1\""
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
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])
