The
GaussJordan and
Simplex
programs aid in row reduction
for the Gauss-Jordan method of solving systems of linear equations
and the simplex method of solving linear programming problems.
The
MatrixCalc
program calculates expressions involving
matrix arithmetic. Built in are identity matrices, matrix inversion,
determinants, and many standard scalar functions as well.
The
Graf program draws graphs of functions of one variable.
It can draw families of graphs, parametrized curves, and sequences
of points connected by lines or not. Zooming in and out on a
graph is easy and intuitive. Functions are entered in standard
mathematical notation, with most of the standard functions
available.
