1D CWT using mexh from command not gui

I need to run a 1D continuous wavelet analysis on data using a mexican hat wavelet, however it needs to be conducted ~300 times therefore I need to have it coded rather than within the gui. I understand that there was a question asked a few years back and it seemed there was no functionality for this, and I am hoping that perhaps something has happened since then?
To provide some background information, I am conducting coastal science research on wave capture and I have a time series of water surface elevations that I need to analyse to determine the dominant frequencies through time at a fixed location. I am able to do this using a morlet wavelet, but for this research, I need it to be a mexican hat (ricker). Any assistance would be appreciated.

Hi Rosanne Heart,
I understand that you are facing an issue in finding a command line version of the function to compute 1D CWT using Mexican wavelet.
The documentation of ‘cwt’ only supports morse/bump/amor options. You can refer the following link to use the older version of ‘cwt’ which supports ‘mexh’:
Although the older version is no longer recommended as the newer functions like, ‘icwt’, are not compatible with it.
Hope it helps,
Regards,
Neelanshu
