[WP 34s] Matrix multiplication procedure

[Thomas Klemm]

WP 34S pocket reference

M×                z y x → r
Take two matrix descriptors y and z, and the
integer part of x as the base address of the re-
sult. Returns (Z)·(Y)=(X). All calculations are
done in internal high precision (39 digits).
The fractional part of x is updated to match
the resulting matrix - no overlap checking is
performed.

That is the matrix-descriptor of the result. Make sure it doesn't overlap with z and y.
