Matrix multiplication is an efficient algorithm, which can optimize some one-dimensional recursion to log (n) and find path scheme, so it is a highly applicable algorithm. Matrix is one of the basic concepts in linear algebra. An M × n matrix is a matrix of M × n numbers arranged in M rows and N columns. Duo to it brings a lot of data together in a compact way, it can easily represent some complex models. Matrix multiplication looks strange, but it is actually very useful and widely used.
