Matrix division

[Arno K]

I did not even check that, clear is that it multiplies by B^-1, but you have to be careful (solve X*B=A instead of B*X=A), so I always use the multiplication above in appropriate form. On the mentioned other HP-calcs I used that division as a shortcut when I solved A*X=b, b being a vector, there it did not matter.
