COMPOSE MATRIX 3

PCOM3

CALL SEQUENCE

CALL PCOM3 (XFRMTA, XFRMTB, ERRIND, XFRMTO).

INPUT PARAMETERS

REAL XFRMTA

Matrix A.

REAL XFRMTB

Matrix B.

OUTPUT PARAMETERS

INTEGER ERRIND

Error indicator

REAL XFRMTO

Matrix resulting from the matrix multiplication of A et B.

PHIGS STATE

EFFECT

Returns a homogeneous 4 x 4 matrix which is the product of XFRMTA and XFRMTB (XFRMTA x XFRMTB).

The returned matrix can be used as the transformation matrix for the SET LOCAL TRANSFORMATION MATRIX 3, SET GLOBAL TRANSFORMATION MATRIX 3 and similar functions.

ERRORS

2

Ignoring function, function requires state (PHOP, *,*,*)
