Percent Error
A lot of times, when I am running Matlab simulations I am comparing how close my results are to real measured data. It is always a good idea to prove that your DSP simulation is matching what happens in real life before trusting its accuracy. Below is a the equation for percent error, which I admittedly had to run a google search on before I made this function.
function [per_error] = percent_error(measured, actual)
% Creates the percent error between measured value and actual value
%
% Usage: percent_error(MEASURED, ACTUAL);
%
% Measured is the your result
% Actual is the value that your result should be
%

per_error = abs(( (measured - actual) ./ actual ) * 100);
