The code crashed when rating matrix is a little large, how to fix it?

[sqcheng]

When I run the code with a rating matrix (100000, 10000), the code crashed, and the reported error is attached. When I use a rating matrix (10000, 10000), it works normal. This error seems caused by memeory out. How to fix such error?

Hi, Thanks for your reply. I haven't fixed this problem !!, so I stopped to explore this code. If you can help to fix it, I will continue with this code. Many thanks ^^
