Why does this error occur? Error using cwt>parseinputs (line 510) Invalid number of scalar input arguments. Error in cwt (line 297) fbcell = parseinput​s(Norig,TT​able,varar

function [f_low, f_high, dominant_freq] = autoIdentifyBandwidth(time, dispDataDetrend, sampFreq)

min_scale = 2;

max_scale = min(100, floor(length(dispDataDetrend)/2));

You do not need to pass scales argument explicitly. The scales argument is excluded of cwt function's signature. The minimum and maximum scales are determined automatically based on the energy spread of the wavelet in frequency and time as illustrated in the documentation of cwt.

Thank you for your answer! I mainly want to increase the resolution of the output frequency, and for me, neither the frequency resolution of the default output nor the resolution increased by VoicesPerOctave is enough
