Measures the execution time of a MATLAB function (on average). Uses a fixed test time.

execution_time.m

time_test = 4; % Time each test may last (in seconds)

tic;
t1=0;
ntrials=0;
while (t1<time_test)
    % Do things to be benchmarked
    ntrials=ntrials+1;
    t1=toc;
end
time_coder=t1/ntrials;
