Accurate Computations with Block Checkerboard Pattern Matrices

Accurate Computations with Block Checkerboard Pattern Matrices

In this work, block checkerboard sign pattern matrices are introduced and analyzed. They satisfy the generalized Perron–Frobenius theorem. We study the case related to total positive matrices in order to guarantee bidiagonal decompositions and some linear algebra computations with high relative accu...
