PCA

说明：  用MATLAB对一图象分别用不同小波分解，观察高低频部分进行重构，比较重构误差，再进行阈值消噪，比较消噪前后图象。(MATLAB right one image with different wavelet decomposition, high-low-frequency observations for some remodeling, more reconstruction error and then de-noising, compared before and after image denoising.)

Computational Matrix Algebra with Matlab

说明：  基于matlab的lsb数字水印算法实现( digital watermarking application)

THREE LEVL mli IS designed for three level NPC converter

说明：  这个源代码实在matlab平台上绘制一个语音序列的语谱图，简单易懂，希望对大家有用！(This source code is a matlab platform voice rendering of the language spectrum sequence, easy-to-understand, useful for all of us hope!)

小波变化软件包，里面包含有比较全面的小波变换matlab函数，以及相应的一些实例，可以看看(wavelet transform)

说明：  三电平逆变器基于虚拟矢量的SVPWM各区间矢量作用时间计算。(Three level inverter based on virtual vector SVPWM interval vector action time calculation.)

这个子程序是为了在第二种情况下对联合部分或者生命部分的估计值而编写的。(This routine is for evaluating union or intersection operation under type2. )

线性方程组的直接解法，其中包括追赶法，高斯消元法和高斯—赛德尔的编程方法(chase-after method program of Linear equations )

常微分方程初值问题的数值解法 本程序主要采用经典四阶的R-K方法和四阶Adams预测-校正方法来求解常微分方程的数值解。 (Numerical Solution of Ordinary Differential Problems of this procedure using the classical fourth-order RK method and fourth-order Adams prediction- correction method to solve the numerical solution of ordinary differential equations.)
