半正定矩阵cholesky方法将其分解为两个上下三角矩阵相乘的形式。matlab自带的函数只能分解正定矩阵。并且给出例子。(Semi-definite matrix cholesky method be decomposed into two upper and lower triangular matrices form. matlab built-in function can only be positive definite matrix decomposition.)

This prorgam calculates Bit error rate on awgn channel with a particular Eb/No values and plot the graph of BEP(Bit Error Probability) against Eb/No.

本程序主要用于利用Matlab对信号波形包络提取进行仿真实现。(This procedure used mainly for the use of Matlab to extract the signal envelope waveform simulation implementation.)

k均值聚类程序，虽然matlab中也有自带的，但是这个速度不错。(program for k means used for cluster)

三相SVPWM整流逆变，波形还ok，仅供参考，欢迎拍砖(three phase svpwm converter ，it‘s good)

关于matlab数学统计方面的程序。包括支持向量机，混合高斯模型等等。(Matlab mathematical statistics on the procedure. Including support vector machines, Gaussian mixture model, and so on.)

声波波场快照程序，可以自己再做进一步的修改。非常好用。(Acoustic wave field snapshots Program)

二维的FDTD,一个连续的脉冲源的传播，边界为PML(Two-dimensional FDTD, a continuous pulse source propagation, the boundary for the PML)

说明：  数字图像处理(实验二) 图像的读、写、显示和点运算 1、掌握函数imadjust与对数和对比度拉伸变换； 2、掌握直方图的绘制和直方图均衡化变换； 3、掌握空间滤波。 (Digital image processing (Experiment 2). the image to read, write, display and point operations a master function imadjust with the number and contrast stretching transformation 2, control histogram drawing and the histogram equalization transformation 3, master spatial filtering .)
