SUBROUTINE slIMXV (RM, VA, VB)
- - - - -
I M X V
- - - - -
Performs the 3-D backward unitary transformation:
vector VB = (inverse of matrix RM) * vector VA
(single precision)
(n.b. the matrix must be unitary, as this routine assumes that
the inverse and transpose are identical)
Given:
RM real(3,3) matrix
VA real(3) vector
Returned:
VB real(3) result vector
