MATLAB killed in Linux

Hi all,

I'm running my code with a elasto-dynamics model, which has 300 degrees of freedom and 300 time steps, and this problem needs to be calculated repeatedly for 225 * 50 times (with a changing parameter).

It takes quite long time so I left the computer running by itself, when I came back terminal showed "killed". After some search I realized that I'd either need more memory or optimize my code. With option 1 impossible for now, I'd need option 2.

I tried to find out the structural fields which cost most memory in each iteration and set them to empty (var = []), but it did not seem working, still got killed. Is there a way in MATLAB like profile viewer, which tells me where cost memory the most?

Thanks!
