Hello everyone
Thank you very much for your help in advance
I have used the 2 different continuous wavelet transform MATLAB code as follow,
First one is https://www.mathworks.com/help/wavelet/ref/cwtold.html
And second one is https://www.mathworks.com/help/wavelet/ref/cwt.html#mw_c5d60d59-2768-4634-a322-93311a78fd8c
The first one was introduced before 2006 but the second on was introduced before 2016. (the second one is the last updated version)
However, after I used these two MATLAB code to perform the continuous wavelet transform, I found that the results are totally different. [I have attached 3 photos including analyzing signal, first result and second result]
From the photo attached above, we can see that the wavelet coefficient are different comparing to each other.
Could anybody please tell me the reason why I got the different results?
and how can we recognize that which result is correct?
PS. I performed cwt using MATLAB-2019a
Thank you very much for your kindness
