matlab tips

[-] use length(x) instead of max(size(x)) in most of my case.
[-] eval?

[-] Remove the ticks from a drawing.
set(gca, 'XTick', []);
set(gca, 'YTick', []);


[-] Matlab automatically resizes the matrix. To avoid frequent reallocations, preallocate the matrix with the zeros command.

a = zeros(1,8000).
If the final array size can vary? cut the excess after the loop.

a = zeros(1, 10000);
count = 0;
for ...

a = a(1:count); % trim the result

If you have complex code that's resource hungry, find the bottlenecks by profiling your code:
