+      SUBROUTINE slMXM (A, B, C)
+
+     - - - -
+      M X M
+     - - - -
+
+  Product of two 3x3 matrices:
+      matrix C  =  matrix A  x  matrix B
+
+  (single precision)
+
+  Given:
+      A      real(3,3)        matrix
+      B      real(3,3)        matrix
+
+  Returned:
+      C      real(3,3)        matrix result
+
+  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 the VAX and many other systems even if this
+  rule is violated.
