一些关于压缩感知（CS）的小程序，主要是压缩感知的重构算法-Some compression perception (CS) program, compressed sensing reconstruction algorithm

python notebook file compressed sensing using FFT and DCT. where, Both both A and 5 keys are presssed and # sampling rate Fs = 40e3 duration = 1./8 N_samps = int(np.floor(duration*Fs)) # Number of compressed basis functions # i.e.
