matlab使用手册，很有帮助作用的，对于查找函数。(matlab manual, helpful role, for the search function.)

相位图像的相位解包算法对一个相位图进行解包裹(Phase image of phase unwrapping algorithm for a phase map unwrapping)

用matlab实现FFT，不是用matlab自带的函数fft，而是自己重新编程(Matlab implementation with FFT, not the native function with matlab fft, but his re-programming)

改进后的游程编码，可以继续量化编码转化为二进制数据流，针对一些较为接近的数，通过合适的阈值设定可以近似，从而大大压缩数据流(The improved run-length coding, can continue to quantify the code into binary data stream, for some of the more close to the number set by appropriate threshold can be approximated, thereby greatly compressed data stream)

基于角谱法衍射理论的近场菲涅尔衍射的模拟(Fresnel diffraction stimulation based on angular spectral method)

这是我自己编写的产生PWM波的MATLAB程序，由于PWM波在信号变换领域很有用，希望对大家有所帮助~(This is my own writing production PWM wave of MATLAB, due to the PWM wave in the signal transformation field is very useful, hope to be helpful to you ~ )
