| ##### 7.7.7.0. iv2lpMat Procedure from library `fpadim.lib` (see fpadim_lib). Usage: iv2lpMat(M); M an intmat Return: ideal Purpose: Converting an intmat into an ideal of the corresponding monomials Assume: - The rows of M must correspond to Letterplace monomials - basering has to be a Letterplace ring Example:
    LIB "fpadim.lib";
    ring r = 0,(x,y,z),dp;
    def R = makeLetterplaceRing(5); // constructs a Letterplace ring
    setring R; // sets basering to Letterplace ring
    intmat u[3][1] = 1,1,2; intmat v[1][3] = 2,1,3; intmat w[2][3] = 3,1,1,2,3,1;
    // defines intmats of different size containing intvec representations of
    // monomials as rows
    iv2lpMat(u); // returns the monomials contained in u
    ==> _[1]=x(1)
    ==> _[2]=x(1)
    ==> _[3]=y(1)
    iv2lpMat(v); // returns the monomials contained in v
    ==> _[1]=y(1)*x(2)*z(3)
    iv2lpMat(w); // returns the monomials contained in w
    ==> _[1]=z(1)*x(2)*x(3)
    ==> _[2]=y(1)*z(2)*x(3)
