Finding significant peaks with MATLAB
WebAug 31, 2024 · It will allow you to interactively find the right settings to identify your peaks. If you prefer to do it programmatically, look into the findpeaks function. Once you have the indices of the peaks, you can use the text function to label them in your plot. WebDescription example pks = findpeaks (data) returns a vector with the local maxima (peaks) of the input signal vector, data. A local peak is a data sample that is either larger than its two neighboring samples or is equal to Inf. The peaks are output in order of occurrence. Non- Inf signal endpoints are excluded. tasting tuscany wine
