I'm currently studying wavelets and am running into confusion with regards to CWT coefficients. Ideally, I want a CWT algorithm that produces outputs similar to that of a STFT - i.e. produces coefficients that correspond to frequency magnitudes of the input signal. However, I'm finding conflicting results.
From the CWT Wikipedia page, I'm given the illustration below. This illustration shows that the wavelet coefficients are essentially just sampling different subbands of the signal. This is not what I'm looking for.
However, when I look at a MATLAB web page discussing the CWT and DWT, I find a different illustration of the CWT when operating on the same input signal. This diagram looks more similar to what I was hoping for where each frequency has a constant coefficient.
What is the difference between CWTs?
