wavelet2 function: Suggest an alternative

I am refering a book on Wavelet Transform for MATLAB code namely, 'An introduction to Wavelet Transform: A signal processing approach' by S.V. Narasimhan, Nandini Basumallick and S. Veena. It seems to have been using a very old MATLAB for coding the plots. It uses the function 'Wavelet2'. It is unavailable in 2020 version. Can you suggest an alternative?

Hi @Sachin Motwani,

The 'wavelet2' function is unavailable in the R2020a version of MATLAB, the Wavelet Toolbox can be utilized instead. It offers a wide range of functions for performing wavelet analysis including functions such as 'cwt' for Continuous Wavelet Transform, 'dwt' for Discrete Wavelet Transform, and 'modwt' for Maximal Overlap Discrete Wavelet Transform, designed to meet various analytical needs.

For more detailed information and examples you may refer to the following documentation:

I hope this helps!
