M.E. Horn: More Examples of Non-Square Matrix Inverses


Martin Erik Horn: More Examples of Non-Square Matrix Inverses. Extended version of the paper “Inverse von Rechteck-Matrizen”

Abstract: In conventional linear algebra the discussion of matrix inverses is usually limited to inverses of square matrices. But Geometric Algebra opens a didactical path to find and to discuss (left-sided) inverses of non-square matrices as well.
It is shown with examples from business mathematics how such inverses of non-square matrices can be constructed and how they can be used to model economic situations.
