Hi, I am running free vibration of shell using [v,d]=eig(kk,mm),where size of kk and mm is 2646. eig is a command to calculate eigenvalues.It takes around 15 min to compute.I am using HP Z800 workstation having 12 processors with 24GB ram in a single machine. Matlab uses only one processor .How can I make it use all processors so that the computational time will be minimal.I am using Matlab R2010a. Thanku

It should use multiple cores automatically. How exactly are you diagnosing that only one processor is being used. Assuming Windows OS, does the Task Manager show only 1 active thread, or is it just that the CPU Usage is 8%?

Hi Matt J, Matlab is just using around 2.5 GB ram out of 24GB. Remaining 19/20 GB is not being used.what I need to do so that Matlab will use more memory.

How did RAM suddenly become the issue? You asked initially about CPU usage, not RAM usage. It is the CPU usage that will dictate computation time.
