Lecture 13 Linear dynamical systems with inputs & outputs
Linear dynamical systems with inputs & outputs • inputs & outputs: interpretations • transfer matrix • impulse and step matrices • examples 13–1. Inputs & outputs recall continuous-time time-invariant LDS has form x˙ = Ax+Bu, y = Cx+Du • Ax is called the drift term (of x˙)

Lecture 3 Linear Equations and Matrices
see.stanford.eduso multiplication by matrix inverse solves a set of linear equations some comments: • x = A−1b makes solving set of 100 linear equations in 100 variables look simple, but the notation is hiding alot of work!

Solving a system of linear inequalities is similar to solving system of linear equations but with inequalities we are not finding a point (or points) of intersect. Instead the solution set will be the region that satisfies all of the linear inequalities. The best way to solve a system of linear
