matrix.
INV Inverts square matrix.
MUL Multiplies two matrices or a
vector and a matrix.
Table 4-5 through Table 4-6 give more information about the MAT =
statement.
Table 4-5 Gives the new dimensions of and value of
num_array1
for
each form of the MAT = statement.
Table 4-6 Shows how the dimensions of
num_array2
and
num_array3
determine the new dimensions of
num_array1
.
