An Algorithm for Solving the Absolute Value Equation

Abstrakt

Presented is an algorithm which for each $A,B\in\Rnn$ and $b\in\Rn$ in a finite number of steps either finds a solution of the equation $Ax+B|x|=b$, or states existence of a singular matrix $S$ satisfying $|S-A|\leq |B|$ (and in most cases also constructs such an $S$).
