I have a huge data for which I want to apply wavelet and plot scalogram. the below code works for small data. However, I have a huge signal, for which I am not able to plot scalogram.

Can anyone suggest possible way to

wname = 'morl'; scales=1:64; coefs = cwt(Signal,scales,wname);%'scalCNT'); TAB_Sca2Frq = scal2frq(scales,wname,1/fs); z=wscalogram('image',coefs,TAB_Sca2Frq,Signal);
