Math551 – Goal: In this assignment, you will use Matlab to visualize the action of a 2×2 matrix A. You will practice thinking of A as a type of abstract system that takes as input a 2-vector x and produces as output another 2vector Ax (the matrix-vector product). Using a common engineering style for representing abstract systems, A can be represented as follows. Solved

Math551 – Goal: In this lab, we will consider the “best” way to solve a linear system of the form Ax = b. Of course, in order to understand what “best” means, we need some means of comparison. For this exercise, we will compare methods based on their accuracy and efficiency. Solved

Math551 – Goals: You will use Matlab to analyze a worldwide air transportation network . The data are over a decade old by now, but still usable for our purposes. In the vocabulary of Section 2.4, the network is represented as an undirected graph with cities (not airports) represented as vertices and with an edge connecting two vertices if it is (or was at the time the data were collected, rather) possible to fly between the two cities. Below is a small portion of this graph, showing some of the cities reachable in two hops from Manhattan at the time. From here, you can get a sense of the age of the data. Note that the vertices are not intended to indicate geographic locations; the only information the graph is intended to convey is the presence or absence of a connecting flight between cities. Solved
