MathGL - library for scientific data visualization. MathGL is a library for making high-quality scientific graphics under Linux and Windows. It is useful for fast data plotting and data proc- essing of large data arrays. Supports working in window and console modes and for easy embedding into other programs. Has a large and still growing set of graphics. It can be compiled with several different options, however, since with basic Slackware installation most of them are already present, only three optional configuration flags are present, and represent optional dependencies: GSL -- GNU Scientific Library, GNU Octave (a Matlab clone) and openmpi, all of which are accessible on slackbuilds.org. GSL=yes (for GSL support, needs gsl) OCTAVE=yes (for Octave support, needs octave) OPENMPI=yes (for Open MPI support, needs openmpi) add the ones needed when launching the slackbuilds, like GSL=yes OCTAVE=yes ./mathgl.SlackBuild
