自适应信号处理，英文版的！！史坦福大学Bernard Widrow写的(Adaptive signal processing, the English version! ! Written by Bernard Widrow Stanford University)

This file contains matlab simulation for vector control for induction machine.

该代码是Crystal地震模型的数值模拟，运行较慢(This codes is written for Seismic Crystal Simulations )

本代码实现基于Retinex理论的三种方法，分别为单尺度Retinex，多尺度Retinex，以及自商图像方法。直接运行每个文件夹下的test文件就可以得到对应的方法的处理结果。(This code implements three methods based on Retinex theory, respectively, for the single-scale Retinex, the multiscale Retinex, as well as self-quotient image method. The test file can be run directly under each folder corresponds to the method of processing results.)
