SLA_MXM - Multiply $3\times3$ Matrices

ACTION:

Product of two $3\times3$ matrices (single precision).

CALL:

CALL sla_MXM (A, B, C)

GIVEN:

B R(3,3) matrix B

RETURNED:

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

NOTE:

To comply with the ANSI Fortran 77 standard, A, B and C must be different arrays. The routine is, in fact, coded so as to work properly on the VAX and many other systems even if this rule is violated, something that is not, however, recommended.
