Matrix Introduction
As is the corresponding two kinds of matrix (3 rows and two columns, two rows and three columns), and a method of obtaining an intermediate corresponding to a certain element
Matrix Operations
The above two cases is more based content, here are a matrix multiplication
In the above calculation, it can be seen that the present matrix multiplication conditions
Matrix
First, the matrix is a square, and secondly, only the contents of the above angle of 1, 0 elsewhere
Transposed matrix
In fact transposed matrix of rows and columns of a matrix of mutual conversion
Inverse matrix
The above after multiplying matrices A and its corresponding inverse matrix, a matrix is obtained, the matrix A can be obtained and the corresponding inverse matrix is square
