Purpose: To learn how to get and use matrices from the Market Market and the University of Florida Sparse Matrix Collection. Also to learn about Matlab utilities for solving and displaying sparse matrices. Prerequisite: Knowledge of using Gaussian elimination to solve Ax = b (for example Sections 1.3 and 1.4 of Spence, Insel and Friedberg).

Jan 20, 2009 · The coefficient matrix, A, is the same, but we have n right-hand side columns of known values. Each of these columns of known values corresponds to one column of unknowns in the B matrix that is A-1. If we use our usual process for solving Ax = b, with, for example, b = [1 0 0 0 …0]T, we will obtain the first column of B = A-1.

The existence and uniqueness of solutions to Ax = b is stated below. If the rank of the original matrix, A, equals the rank of the augmented matrix, [A,b], equals the number of rows, n, there is a unique solution to the matrix equation, Ax = b. If the rank of the original matrix, A, equals the rank of the augmented matrix, [A,b], but is less ...
