# trianfml

symbolic triangularization

## Calling Sequence

    [f [,sexp]]=trianfml(f [,sexp])

## 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))
