压缩感知

代码说明：

说明：  matlab程序分别使用了时域稀疏信号和频域稀疏信号进行测试，两种不同在于时域稀疏信号不用稀疏表达矩阵（因此稀疏表达矩阵使用单位阵即可），而频域稀疏信号则需要先通过稀疏表达矩阵将信号在频域进行稀疏表示，再压缩感知后进行恢复时也要进行反FFT变换到时域。(The matlab program uses sparse signal in time domain and sparse signal in frequency domain to test. The difference is that sparse signal in time domain does not need sparse expression matrix (so sparse expression matrix can use unit matrix). Sparse signal in frequency domain needs to be sparsely expressed in frequency domain by sparse expression matrix first, and then inverse FFT transform is needed when compressed sensing is restored. To the time domain.)
