ACTION:
 Product of two $3\times 3$
matrices (double precision).

CALL:
CALL sla_DMXM (A, B, C)
GIVEN:
A  D(3,3)  matrix A 

B  D(3,3)  matrix B 

RETURNED:
C  D(3,3)  matrix result: A$\times $B 


NOTE:
 To comply with the ANSI Fortran 77 standard, A, B and C must be different arrays.
However, the routine is coded so as to work properly on many platforms even if this rule
is violated, something that is not, however, recommended.
