I want to outout both a plot that requires two built in functions (plot() and findpeaks() ) and also a matrix that gives the locations, heights, and peak to peak interval. As this function stands, it only outputs the graph. is there anyway to get it to output the matrix as well?

function [myplot,mypeaks,mymatrix] = peaks(d)
myplot = plot(1:length(d), d);
mypeaks = findpeaks(d,'MinPeakDistance',50, 'MinPeakHeight', 10);
[height,locs] = findpeaks(d,'MinPeakDistance',50, 'MinPeakHeight', 10);
pp = [];
for i = 1:length(locs)-1
    pp(i) = locs(i+1)-locs(i);
end
pp = [0, pp];
mymatrix = [locs(:), height(:), pp(:)];
end
