====== Math 445 exam 1 topics ====== Exam 1 (Thursday March 3, 2016 10:10-11:00am DeMeritt 240) will cover lecture and labs to date. That said, I can list a few things about Matlab that you really must have a solid grasp on for the exam. * Vectors and matrices: how to create them, how to access and set their elements, and how to perform mathematical operations with them. * The difference between elementwise and linear algebra operations on vectors and matrices. * How to set up and solve systems of equations using vectors, matrices, and the backslash operator. * The colon operator: how to use it to specify sequences of numbers and access subvectors and submatrices. * Plotting: how to make $xy$-plots of functions, how to label their axes, color the lines, display a coordinate grid, etc. * Log-linear relations: how to make logarithmic plots, and how to infer a functional relation $y=f(x)$ given a logarithmic or linear plot. * **for** loops: how to repeat an action a number of times with a **for** loop. * **fprintf**: how to do basic formatted output with **fprintf**. * **function**: how to write your own functions. * scripts: how to write scripts to perform a given sequence of commands. * hamster dynamics / Google Page Rank: how to translate a graph of nodes and links to a transition matrix and then calculate the steady-state distribution.
