Matlab R2007b Plp Is MATLAB Java Based?

Is MATLAB java based? - matlab r2007b plp

I always thought MATLAB (R2007b) is very slow and cumbersome, and I recently noticed, is crumbling as MATLAB was that under the Task Manager (Windows), the icon for the Java coffee cup appeared in several of my figures from Matlab and Tools tool (SISO).

for the software so badly, why Java-based off argh! mobile or not, the system must be (can) in C + + so much more effective.

No idea what Java is associated with the function of Matlab? it's just my version or software?
