Different results with Different version of continuous wavelet transform(cwt)

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
