I am working on the wavelet coefficients of Morlet wavelet. while using cwt(x,scales,'wname') command, how to determine the value of "scales".
Someone said the scales value is related to the center frequency of wavelet, then what is the relationship.
Thanks in advance.

The relationship is far from straightforward. You can use scal2frq in the Wavelet Toolbox to get an approximate scale to frequency conversion for a specified wavelet. To guide you in constructing a scale vector to input into cwt.m, you should think about what scales you wish to investigate and how fine the spacing between those scales should be.
