Description

Symbolic triangularization of the matrix f ; triangularization is performed by elementary row operations; sexp is a set of common expressions stored by the algorithm.

Examples

A=['1','2';'a','b']
W=trianfml([A,string(eye(2,2))])
U=W(:,3:4)
a=5;b=6;
A=evstr(A)
U=evstr(U)
U*A
evstr(W(:,1:2))
