Hi Jakob

This is not possible I think, the best solution for you would be to
reassign U to a smaller value immediately after calculating svd, that
should free up your memory.

Instead of reassigning it, you could also simply call

clear U

after the svd call, but like Oli said, I don't know any way to get around it.
