c Computes matrix product of 3x3 matrices xm1 and xm2

Parameters

xm1	R*4 I Input Matrix
xm2	R*4 I Input Matrix
xm3	R*4 O Output Matrix

◆ oceuler()

void oceuler	(	float	a[3],
		float	xm[3][3]
	)

c Computes coordinate transformation matrix corresponding to Euler c sequence. The order of angles in the input array is yaw, roll, c pitch; according to OSC, the order of the rotations is the reverse c of this; the roll and pitch angles are about the negative Y and Z c axes, respectively, while the yaw angle is about the positive X axis. c Reference: Wertz, Appendix E; OSC, personal communication c Modification history: c c c Modified to change order of rotations to pitch, roll, yaw (-Z, -Y, -X) c F. S. Patt, GSC, September 29, 1996. c c Removed negative signs on Y and Z rotations for OCTS; order of rotations c is yaw, pitch, roll (Z, Y, X)

Parameters

a	R*4 I Input Array of Euler Angles (degrees)
xm	R*4 O Output Transformation Matrix
