The green number in the upper-right box is the fraction of correctly classified entries in that row (and the red is the incorrect).

The green number in the bottom-left box is the fraction of correctly classified entries in that column (and the red is the incorrect).

The green number in the bottom-right corner (grayer than the others) is the overall fraction of correct classification.

================

There are several different methods to do classification, in MATLAB. For example, you could use the Classification Learner App. You can get some of the outputs you want from that. Personally, I have always found it quite quick and easy to just code the definitions myself, given the predicted and actual classes.
