Matlab Become Very Slow After Weka

Hi, i was set maxheap in the RunWeka.ini for Weka become 4000m. It is because of my Weka always OutOfMemory for Machine Learning's training. So the Weka can run normaly without OutOfMemory message now.

But after that, my Matlab become very slow and the accuracy of training data if very decreased. I am using Matlab R2016b.

It is weird...

Is this problem would be done by reinstalling Matlab?

Please help....
