Out of memory error: Java heap space #50

Closed Despair2000 closed 5 years ago

Despair2000 commented 5 years ago

It now happened to me a few times that matlab becomes unresponsive with this java heap space error. It always happens after I downloaded a lot of historical data.

Is this my code or IB4m that makes something strange?

did you update java heap size for Matlab at launch?

I just googled it and found that (should have done so before writing here). I will ramp up the size and try again.

Thanks!

I doubled the heap size and the error vanished.

Thanks!
