Matrices And Linear Systems

Companion software for the Signal Processing & Linear Systems book by B.P. Lathi

The m-file finds the elimination matrices (and scaling matrices) to reduce any A matrix to the identity matrix using the Gauss-Jordan elimination method without pivoting. Using the matrices gotten it computes the inverse of the A matrix.

This book is written for computational scientists who would like to incorporate state-of-the-art computational methods for solving large sparse systems of linear equations.For a full book description and ordering information, please visithttp://www.mathworks.com/support/books/boo...=-1&language=-1

This vector class stores elements in a list and hence allows the 'vector' to grow dynamically. Common mathematical functions (sin, cosh, etc) are supported elementwise and so are a number of 'external' operations (dot for the inner product between vectors, norm, sum etc.).This class does not rely...
