I am running R2017a on a Max OS X 10.12.5 computer. Recently, the program has started crashing whenever I try to save workspace to any location (tried changing filename, directory etc already). I am performing big simulations so that the final size of the workspace is ~20Gb and I have ~50000 x 50000 matrices. Since this never happened before, I am struggling to find a solution for this. Also, it is extremely frustrating because I basically lose all the results every single time and I am completely stuck. Has anyone else had this problem?

Apparently there is no real solution. OS shuts the process down when it is taking too many resources. The workaround I found is to use the save command at every step of the simulations and clear the Workspace as much as possible. If that is not applicable to your case, the only option is probably to buy a bigger computer.
