Scilab DeSktop

Thanks to this new feature, Scilab confirms its usability and

its strong user-oriented approach. Scilab desktop is the new

concept behind Scilab windows management taking

advantage of our docking system (advanced FlexDock

features).

Out of the box, Scilab is now able to save all windows layouts

including the help browser, the variable browser, the

command history, SciNotes and Xcos. Through this major

improvement, position and size of all windows are saved from

a session to another.

File browser

A file browser component has been developed and fully

integrated into Scilab desktop and all other components have

been improved to provide the best user experience for Scilab

users.

Editvar has had important refreshment.

It allows plot and subplot, manages almost all Scilab variable

types and is much more faster.

Scilab desktop provides various predefined layouts:

w Simple: The standard Scilab console

=> Scilab 5.3.3 (and previous versions) defaults.

w Integrated: The variable browser, the history browser

and the file browser are opened by default and combined

around Scilab console to provide an ergonomic

workspace.

=> Scilab 5.4.0 defaults

Variable browser has been improved:

w The dimension of the variable is shown by default.

w The variable browser table is automatically resized

when docked.

w A tooltip has been added on the type column to display

the name of the type.

w A tooltip has been added on the size column to display.

the size in bytes (like in previous versions of Scilab).

w Refresh is automatical.

See Bug # 9446.

A unique Preferences window has been developed

to configure Scilab and its modules.

This unique interface can be launched using preferences()function.

GRaphicS

Entire refactoring of Scilab graphic capabilities in

order to solve the known issues of graphical cards

compatibilities and many Scilab crashes.

Based on SciRenderer (rendering library based on

JoGL), Scilab graphics have been rewritten to

provide new graphic functionalities with:

w Better performances,

w Better stability,

w 2-D zoom using the mouse wheel,

w New 3-D zoom capabilities,

w Rotation available through the mouse right-click.

SciRenderer is a free and open source library developed by

Scilab Enterprises for 2-D and 3-D rendering of scientific data.

Improved graphic exports:

w Off-screen export (Scilab will not open a window to

export with driver).

w New bitmap formats supported: PNG, JPEG and BMP

in the driver function.

w New vectorial formats supported: PDF and SVG in the

driver function.

w Many portability issues fixed.

Obsolete value for line_style property:

0 and 1 are equivalent values for SOLID rendering.

A warning message will be displayed if the user tries to set

this property to 0. Setting this property to 0 will no more be

supported in Scilab 5.4.1.

datatips tool improved on several aspects:

w It is now possible to manage directional arrows as well

as square mark markers.

w The automatic label placement has been improved to

avoid the overlapping with the curve.

w It is now possible to have painted box or box free

labels.

w Markers can now be selected and moved using the

arrow keys or deleted with the "Del" key.

HDF5-based, documented, and fully tested: Scilab Open

Data format (SOD).

sequence save("filename", a, b, c) and writes

data in old Scilab binary format. This format will not be

supported by Scilab 6.

to SOD files.

Calling load with a file descriptor as first input

argument is now obsolete.

Please replace the file descriptor by the corresponding file

name. This feature will be removed in Scilab 6.0.0.

teStS

The assert module provides a set of assertion

functions.

The goal of this module is to provide functions to check the

behavior of some other functions, for example in unitary tests.

We emphasize the use of consistent tools for testing

numerical issues, with the goal of testing numerical algorithms

more easily. In particular, we provide a comparison function

for two floating point numbers, which allows to check that two

numbers are "numerically almost equal", i.e. that the relative

error is small.

This automatically fixes Bug # 4381.

A fourth argument added to test_run to export test

results to XUnit format.

A new function called example_run has been

introduced, this function tests the examples given in

Scilab help pages.

See SEP # 83.

the minimal installation.

peRFoRMaNceS

Under GNU / Linux and Mac OS X, Scilab start-up

speed of scilab-cli and scilab-adv-cli has been

improved by 15 to 20 %

See Compilation for more information.

SSE is now enabled by default under GNU/Linux

with 32-bit CPU (it is already the case under 64-bit

CPU).

required.

Scilab 5.4.0 Release Notes - 12© 2012 - Scilab Enterprises

Improved performances of pareto_filter function

(Genetic algorithms).

hank function performances improved.

Using api_scilab, construction of any type of

lists is now much faster (300x in some cases).

Bug Fix:

w Bug # 8608 fixed - dec2hex, hex2dec, dec2oct,

oct2dec, base2dec code have been simplified and

optimized.

coMpilatioN

Under Windows, Scilab uses VS 2010 Pro and

Express solution.

Under GNU / Linux and Mac OS X, engine libraries

have been merged into a single library named

libscilab-cli.so. This greatly improves the start-up

performances.

Note that the --enable-maintainer-mode enables the

previous behavior (simply the development process).

Under GNU / Linux and Mac OS X, all modules build

as standalone their algorithms as a static library

(only available in the source tree).

This will avoid an important dependency tree for unitary

testing.

Under GNU / Linux and Mac OS X, for each module,

the list of explicit dependencies on the other

libraries is no more needed. Use libscilab-cli.so or

libscilab.so to link against Scilab.

Scilab dependency on Java HDF has been removed.

Enforce a minimal version of JRosetta (1.0.4).

Enforce a minimal version of flexdock (1.2.0).

Enforce a minimal version of GIWS (1.3.0).

Enforce a minimal version of Scirenderer (1.0.2).

Enforce a minimal version of JLaTeXMath (1.0.0).

Enforce a minimal version of JOGL (2.0-rc9).

Force the Java class version target to version 6 (or

1.6).

Add Java 7 in the Debian & Ubuntu search path

under GNU / Linux.

BLAS_LIBS variable can now be set by the user

See Bug # 9824.

Scilab now uses the ARPACK-ng package

maintained by Scilab Enterprises.

An option --without-arpack-ng has been added

to disable the Arnoldi features.

HDF5 is now a mandatory dependency of Scilab

(even in a minimal build).

Under GNU / Linux and Mac OS X, if ccache is

installed, use it to build Scilab.

Bug Fixes:

w Bug # 9409 fixed - Warning "remark #8291" removed

with Intel Fortran 2011 compiler.

w Bug # 9500 fixed - Explicit the GUI module manifest

class-path to facilitate Debian checking tool process.

w Bug # 9782 fixed - Configure with --without-gui

was failing.

w Bug # 9793 fixed - --without-gui now also

disables Xcos.

w Bug # 9883 fixed - Build with

--disable-build-help was failing.

w Bug # 9991 fixed - ./configure --without-xcos

failed to build.

w Bug # 11060 fixed - ccache use can be disabled with

--disable-ccache.

pmodulo(x,0) returned x.

to compute the modulo is x - y * int(x / y) for the

modulo function and x - y * floor(x / y). Now, they

return an error and %nan with ieee(2).

See Bug # 7216.

Scilab 5.4.0 Release Notes - 15© 2012 - Scilab Enterprises

In previous versions, newest function could be

called with a string vector as second (up to last)

input argument.

In these cases, only the first string of the vector was taken into

account. These calls now return an error.

See Bug # 11398.

Setting the 'foreground' property for a figure was

possible even if it was not officially supported or

documented.

An error is now returned. Please use the axes

'foreground' property instead.

See Bug # 11369.

getcallbackobject: Input argument must be an

UID (String) and no more an index (Constant).

Some issues at start-up under Mac OS X 10.6.7 (and

previous 10.6 versions) have been reported.

If you have "Audio Hijack" installed on your Mac OS X, it

prevents some applications to work including Scilab.

See Bug # 7012.

Uninstall / disable Audio Hijack should fix this problem. Airfoil,

also developed by Rogue Amoeba, has been reported as also

breaking Scilab.
