Matrix multiplication can be
performed if the number of col-
umns of the first matrix is equal
to the number of rows of the
second matrix. The sum of these
multiplications (1
is placed in the 1,1 (first row,
first column) position of the re-
sulting matrix. This process is
repeated until each row of A has
been multiplied by each column
of B.
