This error can be caused by several different things, but indicates that the amount of native memory allocated for Java class metadata is exhausted. This probably means that MATLAB has ran out of memory and can be caused by

• Not having enough RAM to perform the actions desired.
• The amount of RAM Java can be used is restricted in MATLAB
• Something outside of MATLAB is restricting the amount of RAM MATLAB can use

To adjust Java Heap Memory Preferences inside of MATLAB, see the link below:
