Acceleration peak finder

This function finds the peaks between sign changes

% This function simply finds the peak of a signal between a sign change.
% This is the peak of a two sided signal. There is only one input
% which is the array. If you had data from an
% acelerometer you would simply input the 1Xwhatever array of values
% and it returns the following: an array with the peaks, the mean value
% of the peaks, and an array with the peak locations

% to use simply >>peakydo(nameofyourarray) or you
% could enter >>[x y z]=peakydo(nameofyourarray)
