I also wondered if that was the case since the size was the same - but both a and b matrices returned as 0 0 after the MATRIX 0 command. Like the memory space had not been reclaimed. Still, it happened only once this morning and the calculator works wonderfully before and after, otherwise.

Strange, but maybe worth to investigate.
Did you use other special functions that claim for free registers, such as complex mode, integrate/solve?
What kind of matrix operations did you use, roughly, if you can remember?
Any use of the MATRIX 2 and 3 operations that change the matrix size?
Did you use only two 8x8 matrices, or also a vector for system solving?
No program step at all?
