introduction to power electronics and its applications

压缩感知中一种非常典型的梯度投影算法，算法的速度非常快(Compressed sensing in a very typical gradient projection algorithm, the algorithm is very fast)

MATLAB描点，数据量有一万多。把一万多个点描到图上。真的有以往多个点，数据量很大了吧。(MATLAB describe points, more than 10,000 of the amount of data. More than 10,000 pointillism to the map. Really have more points in the past, large amounts of data it.)

Daugman虹膜识别方法的研究,利用2_D Gabor filter进行Iris Recognition. MATLAB实现基于Daugman的虹膜提取算法源代码Iris-Segmentation(Daugman iris recognition method, using 2_D Gabor filter for Iris Recognition.MATLAB based on Daugman)

惠更斯-菲涅尔衍射计算，非常不错，简单易行。(Huygens- Fresnel diffraction calculations, very good, easy.)

利用沈左右算子及直方图信息，提取目标区域的纹理特征。(Shen and histogram information about operator is employed to extract texture features of the target area )

正确率可以达到98％，匹配追踪和正交匹配追踪，基于分段非线性权重值的Pso算法。( Accuracy can reach 98 , Matching Pursuit and orthogonal matching pursuit, Based on piecewise nonlinear weight value Pso algorithm.)

说明：  关于空间矢量控制的程序，对于异步电机矢量控制具有参考意义(On space vector control procedures for the induction motor vector control with reference value)

Hilbert变换，经过测试，与matlab一致(Hilbert transform, tested, consistent with matlab)
