Https://www.vijos.org/p/1067 It is easy to introduce the recursive formula F [N] = f [n-1] + F [N-2] +... + F [n-k]. Methods of constructing a matrix: To construct a K * k matrix, where the upper right corner of the (k-1) * (k-1) matrix is the unit matrix, each number in the k-th row corresponds to the coefficients of

MATLAB Image Processing day9: 1. Permute (): The % permute function is used to rearrange the array and swap the dimension of the array. % For a two-dimensional array, the permute function can be used to transpose the matrix. Sample: 2. Differences between matrix A and matrix: A' indicates the transpose matrix of. 3
