Solution of Linear Systems Systems of Linear Equations Consider the linear system Ax = b where A is an (n x n) matrix, x is the vector of (n) unknown solution values, and b is a column vector of constants Solution of a Linear System A formal way to obtain a solution using matrix ...
On data from the Harwell-Boeing collection, we find that LU factors of A are usually more efficient, but the new approach performs reasonably on sparse banded systems such as those arising from 2-D and 3-D finite-difference grids. Key words. sparse linear equations, direct methods, ...
