I'm using a HP Z840 workstation, it's a bit of a beast with two processors (E5-2643) and 128GB RAM. Is there anyway to speed up Matlab processes with this? Or does matlab just run as fast as it can? I'm aware the RAM lets me run larger arrays but is there anything else I can do? Or is it all done by default?

在 MATLAB Online 中打开

In your command window, type

ver

and check out if you have the parallel toolbox. It will be an entry like

Parallel Computing Toolbox Version X.Y (R201RR)

If so, it would be worth investing a little time studying what this toolbox offers (explicit parallelism), as mentioned by Edric below.

Thank you for the clarification, I'll take a look

MATLAB runs as fast as it can. MATLAB will automatically use parallel computing for sufficiently large mathematical calculations that match some patterns.

Sometimes it helps to explicitly code parallel programs using parfor or spmd or similar. Not as often as you might guess at first, though: the communication overhead can make it slower.
