At the same time, the calculation of the Nth power of the matrix is also a common problem in the study of higher algebra and linear algebra. This paper first introduces common methods for calculating the higher power of the matrix. Then, starting from the properties of the special matrix with rank 1, using its properties, combined with the binomial theorem, the formula for finding a matrix consisting of rank 1 matrix and quantitative matrix is given, and the method of how to judge this kind of matrix is given. At the same time, the relationship between the rank 1 matrix and the idempotent matrix is established, and the properties of the idempotent matrix are used. The higher power method of the corresponding matrix is given.
