指纹识别算法的matlab程序，用的算法是gabor滤波器(matlab program of fingerprint recognition algorithm , using the algorithm of gabor filter)

I uploaded sample code for SIMPLE-algorithm and solving lid-driven cavity flow test. It has a lot of shortcomings, but I think that it will be useful for all newcomers. I intend to develop it further, but now it very slowly converges. All notes will be useful, and hope it can be discussed.
