57 ... 64] (only integers, without dots).

But impossible to calculate
EXP (M9),
with M9 containing only integers, as not enough memory.

A couple of notes:
A 64 x 64 matrix is approaching the limits of memory for the HP 50, especially if the calculation involves other matrices.

You don't need to delete the dots to make the matrix exact, just use :: R\->I MAP or \->Q\pi.

I am following this thread with great interest. I have experimented with general programs to apply functions to matrices using SVD (singular value decomposition) but the results have been disappointing, especially for EXP and LN. I am hoping that the two of you (and others!) will come up with a good solution.
