[pk,lc] = findpeaks (s,t); hold on plot (lc,pk, 'x') Use the 'Threshold' name-value pair to exclude the flat peaks. Require a minimum amplitude difference of 1 0 - 4 between a peak and its neighbors.
WebSome minor caveats. This function returns peak indices in reverse order of the R code. It requires a inhouse C++ Sign function, which I included. It has not been completely optimized but any further performance gains aren't expected. //This function returns the sign of a given real valued double. WebMay 26, 2024 · Answers (1) In your above line of code, you are indexing x2 from elements 90 through 120 and not from between the values of 90 and 120. To find the indices of x2 with values in your preferred range use the following instead. % Between 90 and 120, but not equal to 90 or 120. Using the correct index, use the following with findpeaks.
WebFindPeaks [ list] gives positions and values of the detected peaks in list. FindPeaks [ list, σ] finds peaks that survive Gaussian blurring up to scale σ.
