This package will allow you to access routines that go beyond the MAXIMA that is installed by default, such as a package to work, for example, with Linear Algebra [load ("linearalgebra"); ], to use the Simplex Method in Operational Research [load ("simplex"); ] and several others. The description above is basically that of MAXIMA and does not explain what this installation will allow. I strongly suggest that everyone has this feature installed together with MAXIMA
