The multiplication of the two matrices needs to be similar to the following: (3x2)x(2x3), (3x3)x(3x1).
Matrix multiplication is an efficient algorithm that can optimize some one-dimensional recursive to log( n ), and can also find path schemes, etc., 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. Because it puts a lot of data together in a compact way, sometimes it's easy to represent some complex models. Matrix multiplication looks strange, but it's actually very useful and has a wide range of applications.
