If A
is an m×n matrix and B
is
an n×p matrix, then A*B
is the
m×p matrix multiplication product C
.
PSPP reports an error if the number of columns in A
differs
from the number of rows in B
.
The *
operator performs elementwise multiplication (see above)
if one of its operands is a scalar.
No built-in operator yields the inverse of matrix multiplication.
Instead, multiply by the result of INV
or GINV
.
Some examples:
{1, 2, 3} * {4; 5; 6} | ⇒ | 32 |
{4; 5; 6} * {1, 2, 3} | ⇒ | {4, 8, 12; |
