Hi @Yashwan,

Please refer to this MATLAB Answer post: Alternative to 'findpeaks' - MATLAB Answers - MATLAB Central (mathworks.com)

In R2023a you should have the islocalmax function, that does essentially the same as findpeaks, although with slightly different output. You will have to use the find function to get the numerical indices of tthe peaks from tthe logical vector islocalmax returns.
