I have the texture the wavelength as in the figure attachment. I want to calculate the distance from one peak to one peak as show in the figure. How can I calculate it ? thank you very much

Consider using the smoothdata function to eliminate the high-frequency noise. After that, first, use the detrend function to remove the varying baseline (this makles the peak amplitudes and location determinations more reliable), then use findpeaks or islocalmax to locate the peaks. (There are other options if detrend does not produce acceptable results, however it is always the first option I use.)
