You need to think about which parts of your code can be run in parallel.
One option can be use to parfor loops instead of for loops. This only works if your loop code does not depend on the output of previous loop.

if you have parallel computing toolbox, this must be the best option to take.

You don't need to be bothered with the hastle you would need to work on without the toolbox.

most of the time, untuned parallel code is slower than the original code, and most of the time, editing code to be faster with parallel toolbox is a hassle.
Never use the Parallel Computing toolbox with the expectation that you will avoid hassle by using it. However with experience sometimes the hassle is not bad, and sometimes you can get pretty good performance improvements.
