borel

Yields the matrix with the same target as the matrix m , whose columns generate the smallest Borel fixed submodule containing the lead monomials of the columns of m .

For example, if R = ZZ/101[a..f], then

     i1 = R = ZZ/101[a..e]
     
     o1 = R
     
     o1 : PolynomialRing
     

     i2 = borel matrix {{a*d*e, b^2}}
     
     o2 = | a2 ab b2 ac2 acd ad2 ace ade |
     
                  1       8
     o2 : Matrix R  <--- R
