Simulink Error: LINK1248: image size exceeds maximum allowable size, what should be done?

Hi everyone,

I should build a matrix with the size of 4851 X 4851 in my simulink model which needs much more memory size and because of that i'm recieving the error: fatal error LNK1248: image size (F85C8000) exceeds maximum allowable size (80000000) I use x64 platform and i have used many suggested options like deviding the matrix into smaller matrices but no change is occured. can anybody tell me what should i do?

tnx
