Can you control the RAM usage in quadratic programming?

Hi,
My current machine has 24 cores and 48GB RAM. My code has a minimization step with quadprog, which, though fast, takes a lot of RAM (I think around 16GB?), so I can only use a few cores when parallelizing my code, which has other slower steps. Is it possible to limit the RAM usage of quadprog to make it a little slower, but allow more cores to be used, leading to a faster result?

Hi, While limiting the amount of memory consumed by a single thread might not be possible, MATLAB does allow you to specify the maximum array size you can create.
Please see this MATLAB Central thread for more information.
