Abstract: We have previously presented various plane rotation patterns, which provide stable O(N2) algorithms for reducing a b-band matrix of order N bordered by p rows and/or columns to (b + p)-band form, where b greater-than-or-equal-to 1 and p greater-than-or-equal-to 1. By splitting the matrix into two similarly structured submatrices and chasing nonzeros to the corners in two directions, the newly proposed patterns reduce the computational cost by 50% compared to the other existing one-way chasing algorithms.
