Positive definite matrices play a central role in mathematics, physics, statistics and engineering due to their unique properties and widespread applicability. These matrices, which are characterised ...

Abstract: This report presents a procedure for simultaneously inverting a number of posi tive-definite matr ices on the Massively Parallel Processor (MPP) by assigning each matrix to a separate square ...
