基于MATLAB的岩体地质2维结构面网络模拟代码。(Based on MATLAB rock geological 2-dimensional network simulation code.)

说明：  关键点提取可以用来提取图像的边缘 这个程序还不错 分享下(the key points extraction can be used to extract the edge of the image . This program is good to share)

Player fills a number from 1 to 9 into given empty space with a rule that no number is appear twice in a single row, column, and minigrid. To play a game of Sudoku, click PlayGame button and an incomplete board of Sudoku will be created in the grid box. Use CheckBoard button to check whether there is a violation in the board. To solve an incomplete Sudoku board, fill the grid box with the corresponding number and click SolveSudoku button. Remember to click ResetBoard before starting a new game or entering an incomplete board to be solved.
