SLA_DMXM

Multiply 3 × 3 Matrices

ACTION:
Product of two 3 × 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×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.
