4.8.3.92. ORIENTATIONMATRIX

ORIENTATIONMATRIX subroutine returns an orientation matrix from an inputted Euler angle.

Table 4.229 Function Name
Language type	Subroutine
FORTRAN	call orientationmatrix (EAtype, EA, A, Errflg)
C/C++	orientationmatrix (EAtype, EA, A, &Errflg)

Table 4.230 Parameter information
Variable Name	Size	Description
EAtype	int	Euler angle type. EAtype should be “313”, “321” or “123” value. “313”: Euler angle ZXZ (Psi, Theta, Phi). “321”: Euler angle ZYX (Yaw-Pitch-Roll). “123”: Euler angle XYZ (Theta_x, Theta_y, Theta_z)
EA	double[3]	An array of double precision type. The array size must be 3. This is input variables as an Euler angle. EA[0] is a 1^st rotate anlge of each Euler angle. EA[1] is a 2^nd rotate angle. EA[2] is a 3^rd rotate angle.
A	double[9]	An array of double precision type. The array size must be 9. This is output variables as an orientation matrix.
error	int	Error flag. If the result of this argument is -1 (means TRUE in Fortran logical value), there is no error. The others mean that there is an error.
