These can provide great starting points
for many people.
If your work leans more toward data
analysis, several popular packages are avail-
able. For all of you Matlab addicts, there is
Scilab. Scilab provides the same types of
functions in an environment familiar to
Matlab users. There also is Maxima, which
provides tools more from a mathematical
background (for example, analyzing func-
tions and doing calculus), as compared to
Scilab’s approach of working from a matrix
background (such as looking at data analy-
sis). Maxima has several front ends available.
The default one in CAELinux is wxMaxima.
If you are doing really heavy statistical
analysis, there is R. The real power of R is
the CRAN repository, and a fair amount is
available out of the box. R also has several
graphical front ends. CAELinux provides
two: R Commander and RKWard. If you are
doing work more along the lines of pure
mathematical analysis, there also is Octave.
The default GUI available within CAELinux
is QtOctave. In all of these cases, text-
based interfaces also are available, if you
are an old-style computer user who prefers
