Problem macbook air slowly performing with Matlab

Hi

I have a Macbook Air 10.9.5, processor 1.7 Ghz Intel Core i7, memory 8 GB 1600 Mhz DDR3 with Matlab R2010b. When I started to use Matlab for performing some simulations I had no problems, but one day it suddenly became very slow. The same simulation now requires around 10 times more time! I saw that Matlab is using 100% of CPU when I perform th simulation but I do not know how to change this. Does someone have the same problem or some hints to solve it? Thanks a lot!

What changed, either on your system or in your simulation, between the last time the simulation ran quickly and the first time it ran slowly? Sometimes something as simple as changing one parameter can impact how long it will take a piece of code to run, like in the flame propagation example in this blog post Cleve wrote.

Is your simulation implemented as MATLAB code, a Simulink model, or something else?
