Abstract
Quaternion least squares QLS problem is one method of solving overdetermined sets of quaternion linear equations AX approx B and AXC approx B that are appropriate when there are errors in the matrix B This paper by means of complex representation and real representation of a quaternion matrix studies the QLS problems and derives two new algebraic techniques for finding solutions of the QLS problem in quaternionic quantum mechanics
