Pseudo-inverse multivariate/matrix-variate distributions

The Moore-Penrose inverse of a singular or nonsquare matrix is not only existent but also unique. In this paper, we derive the Jacobian of the transformation from such a matrix to the transpose of its Moore-Penrose inverse.

Shorter pre-data acquisition time for magnetic particle imaging using AC susceptometry

AIP Advances
Magnetic nanoparticle imaging (MPI) with a detection coil array can be used to estimate the position and quantity of magnetic nanoparticles (MNPs) via inverse problem analysis.

A Singular Inverse of a Matrix by Rank Annihilation

, 1973
Edelblute [1] has given a method of finding an inverse of a nonsingular matrix by rank annihilation. The purpose of this paper is to show that the method can be extended in the case of a singular matrix.

The density of the inverse and pseudo-inverse of a random matrix

Given an absolutely continuous density of a random matrix X, we study the density of the inverse when X is a p x p symmetric, triangular and arbitrary matrix, and the pseudo-inverse when X is rectangular.
