rot_quat_mult

This code allows several different rotation representations to be converted. The representations are:

Quaternion double[4] Angle/Axis double, double[3] Roll/Pitch/Yaw double[3] Rotation matrix double[9] Transform matrix double[16]

Note that these conventions have the property that each representation yields a different function signature. Detailed description starts here.

Multiplies quaternion a with quaternion b and stores the result in c. Arguments a and b must be double-precision floating point arrays of length 4.

Parameters:

	c	Array where the result of the multiplication is stored. Must be at least 4 elements long.
	a	Input quaternion to be multiplied (left-side).
	b	Input quaternion to be multiplied (right-side).
