inline

Left-Inverse of a Matrix.

Computes the Left-Inverse of a Matrix and returns the square root of the gram determinate. For any \( A \in \mathbb{R}^{M \times N} \) (with \( M \geq N \)) the Left-Inverse is defined as

Please note, that in case of a square matrix (i.e. \( N = M \)), the Left- Inverse is identical to the Inverse and the square root of the gram determinante simplifies to the norm of the usual determinate.

Right-Inverse of a Matrix.

Computes the Right-Inverse of a Matrix and returns the square root of the gram determinate. For any \( A \in \mathbb{R}^{M \times N} \) (with \( M \leq N \)) the Right-Inverse is defined as

\[ A^{-1}_{right} := A^T (A A^T)^{-1}, \]

such that \( A A^{-1}_{right} = 1 \). The gram determinate is defined as \( \det{A A^T} \).

Please note, that in case of a square matrix (i.e. \( N = M \)), the Right- Inverse is identical to the Inverse and the square root of the gram determinante simplifies to the norm of the usual determinate.

Parameters

mOut	Right-Inverse of Matrix
m	Matrix

Returns: Square root of gram determinate of Matrix
