Abstract

The matrix equation Av + d = 0, where A is a block tridiagonal matrix, is solved by two methods: a band matrix solver and a block tridiagonal technique. The computation speed of the two methods is comparable. The method which is actually faster will depend on the details of the optimization of each method. 1 table.
