Syntax
residue = Orientation.equalityConstraint(R1, R2);
Description
The function call Orientation.equalityConstrain(R1,R2) returns the Real residue vector
with 3 elements. This vector has zero elements if orientation objects R1 and R2 are identical
(= describe the same orientation). The residue vector is determined by computing the relative
orientation object between R1 and R2 and using the outer-diagonal elements of this matrix to
formulate the residue in such a way that only identical orientation objects lead to a zero residue vector.
