Linear algebra permeates mathematics,perhaps more so than any other single subject.It plays an essential role in pure and applied mathematics,statistics,computer science,and many aspects of physics and engineering.This book conveys in a user-friendly way the basic and advanced techniques of linear algebra from the point of view of a working analyst.The techniques are illustrated by a wide sample of applications and examples that are chosen to highlight the tools of the trade.In short,this is material that many of us wish we had been taught as graduate students.Roughly the first third of the book covers the basic material of a first course in linear algebra.The remaining chapters are devoted to applications drawn from vector calculus,numerical analysis,control theory,complex analysis,convexity and functional analysis.In particular,fixed point theorems,extremal problems,matrix equations,zero location and eigenvalue location problems,and matrices with nonnegative entries are discussed.App

From acclaimed fantasy author Mindee Arnett comes an epic, adventurous story of a young mercenary magic-user trying to escape the oppressive island of Riven--and a young noblewoman trying to change it forever.Mars Darksvane wants out. Out from under the thumb of Una, the crime boss who pulled him off the streets as a child and trained him as an assassin; out from the island country of Riven, where magic, in the form of a dangerous material called Ice, allows the rich to live in luxury and keeps the poor in thrall.Mars is a secret adept--a person born with the ability to channel the magic that flows beneath Riven--and while his power gives him abilities useful to an assassin, it also makes him a target. And when his last mission ends in tragedy, Mars finally decides it's time to escape to the mainland. No magic, no history, a new life on his own.But Una has other ideas. If Mars wants his freedom, he's going to have to perform a final job: protecting Fura Torvald--the heiress of the rich
