I'm trying to write a function that will output the indices of all local maxima and minima of a function. I was able to write code to do so but not within a function. I have this:
function [maxima,minima] = min_max(y)
maxx = islocalmin(y);
minn = islocalmax(y);
maxima = find(maxx == 1);
minima = find(minn == 1);
If i just use the code inside the function it does exactly what I want it to but I'm having trouble getting the function to work properly. The error I'm getting is not enough input arguments. Any advice on how to get this function to execute?
