SIO 221C:  Software Options


Matlab is the software package that students most often use for this course, but you are free to choose any software package or combination of packages that you like, provided that you can carry out computations, invert matrices, and plot results. (http://www.mathworks.com/)  Alternatives to Matlab include:
Octave: a freeware imitator of Matlab, uses almost the same commands.   (http://www.octave.org/)
Scilab: another freeware imitator of Matlab (http://www-rocq.inria.fr/scilab/)
Fortran, c, or c++:  compiled languages.  Run faster than Matlab for some applications,
Lapack/linpack:  Fortran-based matrix inversion packages. (http://www.netlib.org/lapack/)
csh, awk, perl:  Non-compiled scripting languages.  Sometimes very efficient for transforming columns of numbers.  (Not good for matrix inversion.)
GMT:  Generic Mapping Tool.  Free unix command-line software developed for geophysical graphics. (http://gmt.soest.hawaii.edu/)
If you need a copy of Matlab (either for your office or for your personal computer), you can buy the student version at the UCSD bookstore.  You may also want to buy the student version as a way to get a full set of manuals.  Don't use Matlab's older "student edition", which prohibits large matrices and may thwart your ability to get through the problems assigned for this course.
