变尺度法的源程序，用于优化中的非线性规划，效还可以的。(variable scale method of the source for the optimization of nonlinear programming, the effect can be.)

说明：  设计滤波器：设定10个零点，计算出多项式系数，作为滤波器系数； 取出绝对值较大的一半零点，重新设计滤波器；用剩下的绝对值较小的一半零点，重新设计滤波器。(Design a filter: Set of 10 zeros, calculate the polynomial coefficients as filter coefficients remove the larger half of the absolute value of zero, re-design filter with the remaining half of the smaller absolute zero, re-design filter.)

灰度共生矩阵提取特征值，最近邻算法，进行纹理图像分类。creat_apprentissage用来训练样本，cooccurence是灰度共生矩阵提取特征值，knn是进行k最近邻算法，classif是纹理图像分类(coocurence matrix，using K nearest neighbor to classify textures images.)

这里给出了加权OMP的matlab代码，希望此代码能够对研究信号处理的同志有所裨益(Here are weighted OMP of matlab code, I hope this code of signal processing can be beneficial to the comrades)

NSGA原代码，很多人在找这个，对搞智能优化很有帮助(NSGA original code, a lot of people looking for this, very helpful to engage in intelligent optimization)
