Let be a ring. Let the matrices and be partitioned into submatrices and respectively as follows:
where is , ;
where is . Then and (in this ) are said to be conformally partitioned for multiplication.
Now suppose that and are conformally partitioned for multiplication. Let be partitioned as follows:
where is , , . Then
This method of computing is sometimes called block multiplication.
