：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)

MATLAB 特征提取 边界链码（图像处理）(MATLAB boundary chain code feature extraction (image processing))

用MATLAB编写的一个通过积分运算进行衍射计算的小程序。(MATLAB prepared an operation conducted by integral calculation of the diffraction small programs.)

This matlab code is intended to demonstrate the physical significance/interpretation of the elements of diagonal matrix in Singular Value Decomposition (SVD). Here, multiple rows of a BIG matrix is gradually being filled with ones which means the information content is being reduced. Now, the eigenvalues and their 1st and 2nd derivatives are plotted.

信号阵列处理，主要是对四元十字阵和五元十字阵进行了对比，结果显示在只增加一个阵元的情况下效果有明显改善，有一定参考意义(Array signal processing, mainly of quaternary cross array and five yuan cross array are compared, the results showed in the case of only add an array yuan effect has improved significantly, have certain reference significance)
