A Matlab functions and their Scilab Equivalents
Index
Scilab has progressed significantly since I wrote the previous version of this manual (Scilab, then,
was in Version 2.7). The most important improvement, in my mind, is the new graphic system;
then it just became available as an alternative, now it is the only one supported. It appears to
provide all the features that I missed in the original version. Nevertheless, a description of Scilab’s
graphic capabilities is not included here; I continue to believe that they deserve a manual of their
own.
Another improvement is the built-in editor. It works nicely, and it eliminates an annoyance: one can
load a specific function (or all functions) in the editor into Scilab and it is automatically compiled.
No more forgetting to compile a function after it has been changed.
Overall, Scilab functions are even closer to those of Matlab. For example, function “xgetfile” is
now obsolete; its replacement, function “uigetfile” has the same name as the corresponding Matlab
function. This also hints at a change in attitude. Initially, Scilab appeared to be geared towards
Unix/X Windows with MS Windows just an afterthought. Now there are quite a few functions just
for MS Windows. In addition, according to the Scilab team, Scilab runs “out of the box” on Mac
OS X 10.5.5 (Leopard) and 10.6.x (Snow Leopard).
In this updated version of the manual I have removed outdated restrictions or caveats and included
features that have been added to Scilab since Version 2.7. I am grateful to Sylvestre Ledru and
Vincent Couvert, both members of the Scilab Team, for reading the manuscript and providing
feedback that not only improved this manual but also my understanding of the new capabilities of
Scilab.
