## Matlab CWT ( Continuous Wavelet Transform ) Manual Calculation

Started by 4 years ago●4 replies●latest reply 4 years ago●416 viewsHello ,

I am wondering if anyone knows how to manually calculate the CWT step by step and be willing to show me ? Below is the CWT definition :

CWT_x^\psi(\tau,s) = \Psi_x^\psi(\tau,s) = \frac{1}{\sqrt{|s|}} \int x(t) \psi^* \left( \frac{t - \tau}{s} \right) dt

Thanks,

Richard

Richard,

Please see my thesis on the fast wavelet transform. It was a long time ago, but I think there is some Matlab and foundation in there that will help.

Keith,

Thanks for the link / info; I'll check it out.

Richard,

I'd suggest stepping through the CWT function in Matlab using the debug options. Since you are using this function now, understanding its functionality could be a more direct and efficient path to make the changes you want.

Michael,

Thanks for the suggestion !
