| Review: Systems of Linear Algebraic Equations | Paul's On-Line Notes reviewing linear algebraic systems. (We assume that
you have seen this before.) They illustrate solution by elimination. Specifically, they illustrate Gaussian elimination in which an augmented matrix is reduced by elementary row operations to row-echelon form. They discuss determined, underdetermined, and overdetermined systems --- i.e. systems with a unique solution, many solutions, and no solution respectively. |
