Hello everyone my MATLAB is running really really slow. I have a late 2011 Macbook Pro 13' with OSX 10.9.2 with MATLAB R2012a. Every time I try to run a script I get the little blue ball and after a couple of seconds my laptop fan starts to hum like it's really struggling with trying to process the command. Any suggestions on how to fix and/or improve this problem.

yes to the scripts they use to take about no more then a second or so like the results and/or a graph would just pop up and now its like it stalls take seconds to calculate and sometimes it doesn't complete the task and oh I thought that the results from the bench that I should be up higher on the graph. and no I have not tried to analyze the execution with the function profile I'll see what that tells me

Since I know nothing about your scripts I cannot guess what the problem is.
profile will hopefully spot the lines of code which takes so long.

Did you run
bench
? How does it rank your system?
Do you have memory enough for your test?

I know little about MacBook. I googled. Speed a third of that of the top machine seems plausible.
However, the bench result has nothing to do with the problem you encounter.

If you had a parallel computing toolbox as well as its compatible hardware (either CPUs or GPUs), you could be helpful to accelerate the speed.
