I have a total of 89 ECG Signals, for which i have to do time frequency analysis means i have to find the smooth psuedo wigner ville distribution (SPWVD) of all 89 signals. I want to read each signal (one by one), plot their (SPWVD) and save that image into a folder. It means that there are a total of 89 images saved in a folder.
Actually, I am reading each signal, potting their time-frequency transform and then save that image in a folder which is taking too much time. I have also plotted Continous Wavelet Transform (CWT) of these 89 signals for which i uses CWTfilterBank (it loads all signals at once, computes CWT and saves each image to a folder), I cannot find this kind of ease in the former scenario. Can anybody please tell guide me how to find (SPWVD) of all 89 signals (at once or through a loop) and save them in a specific folder?
