WebFeb 2, 2024 · $\begingroup$ For a linear endomorphism on a finite-dimensional vector space to be invertible, it suffices that it is injective. You can see this via the rank--nullity theorem! $\endgroup$ – Jeroen van der Meer WebSep 16, 2024 · This is true if your X is a square matrix. A Matrix is singular (not invertible) if and only if its determinant is null. By the properties of the determinant: det ( A) = det ( A T) And by Binet's theorem: det ( A ⋅ B) = det ( A) det ( B) Then, you're requesting that: det ( X T X) = 0. det ( X T) det ( X) = det ( X) 2 = 0.
