Abstract: This paper introduced concepts of norms of quaternion matrices by means of
complex representation of a quaternion matrix, studied the quaternionic least squares
(QLS) problem and derived an algebraic method of finding solutions of the QLS problem in
quaternionic quantum theory. A numerical example verified the efficiency of the
algorithm.

Key words: complex representation, normal equation , quaternionic least squares, complex representation, normal equation
