WebSep 22, 2024 · On Matlab Central there are several realizations for finding peaks, for example “peakfinder”, “peakseek”, or “peakdetect”. And “findpeaks” is also the name of a function in the Matlab ‘signal’ toolbox. The parameter names are taken from the “findpeaks” function in ‘signal’, but the implementation utilizing regular expressions is unique and fast. WebA function is used to find peaks of the input data or signal is known as Matlab findpeaks. In Matlab, the findpeaks statement gives provision to find the peaks as well as its different …
