[sage-support] Absolute value of matrices

By that I simply mean a function that on input a real matrix M returns the matrix N such that n[i][j] = abs(m[i][j]). This can be achieve by something like: n = len(M.rows()); m =len(M.columns()); N = matrix(n,m,lambda i,j: abs(M[i][j])); However, for a square matrix M, M.abs() returns something
