Algebraic Techniques for Least Squares Problems in Elliptic Complex
Matrix Theory and Their Applications
Abstract
In this study, we introduce concepts of norms of elliptic complex
matrices and derive the least squares solution, the pure imaginary least
squares solution, and the pure real least squares solution with the
least norm for the elliptic complex matrix equation AX=B by using the
real representation of elliptic complex matrices. To prove the
authenticity of our results and to distinguish them from existing ones,
some illustrative examples are also given. Elliptic numbers are
generalized form of complex and so real numbers. Thus, the obtained
results extend, generalize and complement some known least squares
solutions results from the literature.
