[Octave-bug-tracker] [bug #39267] signal package: findpeaks: Error:subscript indices must be either positive integers or logicals

[Juan Pablo Carbajal]

Follow-up Comment #5, bug #39267 (project octave):

Mike,

the implementaton of find peak suses a very rough estimate for the 1st and 2nd
derivative. It wont work correctly on data that is not smooth unless you fine
tune the parameters, check the demos.
findpeaks is a heuristical function, parameters are important and you have to
tune them to get good results.


One possible solution is to implement other methods to find the peaks that are
not based on 1st and 2nd derivative. But at the moment I can't work on it.
