The Degree(A,x) and Ldegree(A,x) commands compute the highest degree and the lowest degree of a matrix of polynomials.

The Degree[row](A,x) and Ldegree[row](A,x) commands compute the highest degree and lowest degree of each row of a matrix of polynomials. The row degree is returned as a list of integers.

The Degree[column](A,x) and Ldegree[column](A,x) commands compute the highest degree and lowest degree of each column of a matrix of polynomials.  The column degree is returned as a list of integers.
