Maximum absolute difference between matrices --------------------------------------------
^matmad^ matrix1 matrix2
Description -----------
^matmad^ calculates for matrices A and B of the same order
max ( | A[i,j] - B[i,j] | ) i,j
Remarks -------
^matmad^ is likely to be most useful for checking the convergence of iterative matrix calculations within programs.
Examples --------
. ^matmad A B^ . ^qui matmad A B^
Saved values ------------
S_1 maximum absolute difference
