Why the old version of CWT code is no longer recommended [Continuous Wavelet Transform]

Hi Everyone!!

My name is Supatat, Now I am doing research about detecting aburpt transition of roll angular velocity of rail vehicle using continuous wavelet transform.

I have used old and new version of cwt code as below.

Newer version:

https://www.mathworks.com/help/wavelet/ref/cwt.html

Older version:

https://www.mathworks.com/help/wavelet/ref/cwtold.html

However, it is stated that the older version is no longer recommended on its webpage.

I would like to know the reason why it is no longer recommended. Does it mean " the result from the old version of cwt code is always incorrect"?

Because I got the different results from old and new version of cwt code. I am confused which one is correct.

Could you please answer me?

Thank you very much for your help in advacne
