Blocking matrix multiply
WebBlock Matrix Multiplication. It is often useful to partition a matrix into smaller matrices, called blocks. A matrix viewed in this way is said to be partitioned into blocks. For … WebApr 5, 2013 · This method gives the fastest result (matrix multiplication goes as O (n^3) and transpose as O (n^2) so doing the transpose is at least 1000x faster). The wiki method without blocking is also fast and does not need a buffer. The blocking method is slower. Another problem with blocking is it has to update the block several times.

WebMAT-0023: Block Matrix Multiplication. It is often useful to consider matrices whose entries are themselves matrices, called blocks. A matrix viewed in this way is said to be partitioned into blocks. For example, writing a matrix B B in the form.
