基于压缩感知的图像处理，分别使用二维DCT、FFT和一维dwt变换对图像信号进行稀疏变换，然后使用正交匹配追踪算法进行重构，在进行相应的逆变换(This is a image processing procedure based on compressed sensing which respectively uses two-dimensional DCT, FFT and one-dimensional dwt transform to sparse the image signal and then uses the orthogonal matching pursuit algorithm for reconstruction.)

This creates a trapezoid wave, similar to the built-in square function but with no duty cycle option

说明：  非常实用的OFDM matlab程序，只有一个m文件，程序简单易懂，包括完整的OFDM调制解调过程，能够正确运行，对OFDM的初学者非常有帮助。(Very useful OFDM matlab program, there is only one m file, the program simple and easy to understand, including the complete OFDM modulation and demodulation process to run correctly on the OFDM beginner very helpful.)

说明：  这是matlab编写的一组神经网络的程序,非常好用,只需要改动一些参数即可(It is written in a matlab neural network program, very easy to use, you can only change some parameters)

一个ram例子，可以参考一下，希望能帮到你，请用winrar解压缩打开。(A ram example, you can refer to, I hope you can help, please use winrar to decompress opened.)
