I do some match computations using MATLAB. The computation may or may not make use of the four multiple cores I have. Suppose that it does make use of multiple cores. Is there a way I can see whether and how many cores are being used? I look at the Activity Monitor but cannot seem to determine how I can see if multiple cores are being used.

see if this is what you are looking for...

This is great. One last question. I have 3.3 GHz Quad-Core Intel Core i7. I guess quad means four cores. But I see 8 cores when I open the CPU Usage or CPU History window. What is going on?

The short answer is, the CPU has 4 physical cores, 8 virtual cores due to hyperthreading.
Thanks a lot.
You're welcome. Here's a brief explanation of hyper-threading.
