Compress a 1D wave
显示 更早的评论
I have a one dimensional waveform that is made from the measurement in an oscilloscope, and am trying to shorten the length of the wave, (that is stored as.a 1999*1 double) to a length of 361, so it looks like essentially the same waveform when plotted.

wave %of size 1999*1
wave(1:361,1) %of size 361*1

the above demonstrates the first 361 elements of that waveform is taken to proceed for further calculations

if there is something not clear let know else accept the answer so other people know the question is solved

You might want to experiment with the different resample methods available.
Another approach is to fft and then ifft with the smaller size specified.
