When I use wdenoise function to denoise, I find the results are different from each run. Is it normal? Thanks a lot for your answers!

Hi wantinga,

Yes, it is normal for the results of the wdenoise function in Matlab to vary slightly from run to run. This is because the wdenoise function uses random numbers in its wavelet thresholding process, which can cause slight variations in the denoising results each time the function is called.

Hope this information is helpful.
