Hi to all,
I use findpeaks function in my code to calculate the four maximum values of a fft function.
I use it in this way:
[maxpeaks, idx] = findpeaks(10*log10(psdx),'MinPeakDistance',195,'NPeaks',4,'MinPeakHeight', -Inf, 'SortStr','descend')
The problem is that I need to run the code in a Matlab version which doesn't have the Signal Processing Toolbox. Is there any solution to write a similar function without the need of the SP Toolbox?
Thank you!

If the MATLAB version is R2017b or later, the islocalmax (link) function is likely the best option.

do you know if it works also on R2017a?

Unfortunately, it won’t. It was introduced in R2017b.
