Matlab multiple cores

I'm running an algorithm that's taking a lot of resources, and maxes out the CPU.

The probl开发者_运维问答em is that it's only using one CPU.

How can i make MATLAB multithread the computations and use more than 1 CPU ?

Unless you specifically use parallel constructs -- that is, using explicit parallelism -- or use built-in functions that have already been parallelized for you -- Matlab will not run faster on a multicore machine. This post has a list of built-in functions that have been parallelized and so will take advantage of multiple cores:

Here's an example of using a parallel construct to roll your own parallelism:
