| ##### 7.7.7.0. iv2lpList Procedure from library `fpadim.lib` (see fpadim_lib). Usage: iv2lpList(L); L a list of intmats Return: ideal Purpose: Converting a list of intmats into an ideal of corresponding monomials Assume: - The rows of each intmat in L must correspond to a Letterplace monomial - 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
    list L = u,v,w;
    print(u); print(v); print(w); // shows the intmats contained in L
    ==>      1
    ==>      1
    ==>      2
    ==>      2     1     3
    ==>      3     1     1
    ==>      2     3     1
    iv2lpList(L); // returns the corresponding monomials as an ideal
    ==> _[1]=x(1)
    ==> _[2]=y(1)
    ==> _[3]=y(1)*x(2)*z(3)
    ==> _[4]=z(1)*x(2)*x(3)
    ==> _[5]=y(1)*z(2)*x(3)
