What are the dependencies for findpeaks.m

You do not place functions in a workspace: you place them in a directory. If you place peakfinder.m in any of the directories that are on your MATLAB path, then it will be found.

As noted earlier, the Signal Processing Toolbox is needed. However, I only needed to process a fairly small and basic array of doubles that could be easily iterated through, so I worked around this by writing my own function as follows:

function [pks, locs] = findpeaks(data)
    pks  = zeros(numel(data), 1);
    locs = zeros(numel(data), 1);
    count = 0;
    for i = 2:(numel(data) - 1)
        if (data(i - 1) < data(i)) && (data(i) > data(i + 1))
            count = count + 1;
            pks(count)  = data(i);
            locs(count) = i;
        end
    end
    pks  = pks(1:count);
    locs = locs(1:count);
end
