^matewd^ matrix1 matrix2 matrix3 [ ^, f^ormat^(^%fmt^)^
Description -----------
Given matrices A and B of the same order, ^matewd^ calculates and displays matrix C with typical element
C[i,j] = A[i,j] / B[i,j]
provided that no B[i,j] is equal to 0.
C may overwrite A or B. A and B may be the same matrix.
Option ------
^format(^%fmt^)^ controls the format with which results are displayed. Default %9.2f.
