Matlab benchmarking

In the following example we test the allocation speed of different types:

samples_to_avg = 10000;
for i=1:samples_to_avg
  tic; t = int8(zeros(32,2^16)); b(i) = toc;
end
avg_int8 = mean(b);
 
for i=1:samples_to_avg
  tic; t = zeros(32,2^16); b(i) = toc;
end
avg_double = mean(b);
 
%int 8 is
disp(['int8 pre-allocation is ', num2str(1 - avg_double/avg_int8), ' times faster than doubles'])
