... With software in this section, you can handle calculations of array-oriented (vector, matrix) data easily without worrying about the detailed programming techniques. Many of the software here contain classical numerical routines like Linpack, Eispack, Lapack , Blas , from Netlib , so that you have access to these powerful numerical linear algebra routines within a single package. ... Classic MATLAB -- freeware (old) MATLAB with linear algebra routines. Euler -- numerical matrix language. ...
