Singular Manual: gaussRowWithoutPerm

| #### D.8.7.5 gaussRowWithoutPerm Procedure from library `recover.lib` (see recover_lib). Usage: gaussRowWithoutPerm(M); M a matrix of constant polynomials Return: matrix: basic Gaussian row reduction of M, just without permuting the rows Example:
    LIB "recover.lib";
    ring r=0,x,dp;
    matrix M[5][4]=0,0,2,1,4,5,1,3,0,9,2,0,8,1,0,6,0,9,4,1;
    print(M);
    ==> 0,0,2,1,
    ==> 4,5,1,3,
    ==> 0,9,2,0,
    ==> 8,1,0,6,
    ==> 0,9,4,1
    print(gaussRowWithoutPerm(M));
    ==> 0,0,2,1,
    ==> 4,5,1,3,
    ==> 0,9,2,0,
    ==> 0,0,0,0,
    ==> 0,0,0,0
