Web1: circular shift of a row (randomly chosen between 1 to N − 1) 2: circular shift of a column (randomly chosen between 1 to N − 1 ) when I shift all the rows and columns I get a scrambled matrix. I want to know if I can get to this scrambled state with fewer shifts. Do I need to solve this problem using graph theory? how? Example : matrix :

WebNov 3, 2011 · Theme SMx = reshape (randperm (9), 3, 3); If you have Matlab 2011b, use "randperm (9, 9)" instead: It uses the Fisher-Yates-Shuffle, which is much faster. And if you struggle with large arrays, this is even faster: FEX: Shuffle. More Answers (2) Fangjun Jiang on 3 Nov 2011 3 Link Helpful (0) I believe it means to be randperm (), not perms (). Theme WebScrambling technology is an image encryption technology. There are many commonly used image scrambling algorithms. This paper first introduces the image scrambling algorithm based on Arnold transform. Then, in order to improve the image scrambling performance, the application of Arnold transform matrix in image scrambling is analyzed.

Proof. Case 1. P has a positive column. (Obviously, in this case, P is a scrambling matrix.) It follows that Pn−1 has a positive column too because the scrambling matrices are row-allowable. Case 2. P has no positive columns. (Obviously, there exist ...
