Do NOT use explicit conditionals (if/else) anywhere in this lab. This chapter (6) comes before the chapter on conditionals (7), so the exercises are designed to be done without conditionals. These functions are all one- or two-liners that should take you a couple of minutes each. In other words, if you're stumped after a few attempts, ASK ME FOR HELP. You should make a new folder for this lab, and put each function (problem) in a separate .m file, named by the function (function foo goes in foo.m). Your comment should be the problem number (D6.3, E6.1, etc.) followed by a brief (one-line) description of what the function does; e.g., your file powersum.m would start with function powersum(z, n) % E6.2 POWERSUM(Z, N) computes sum of Z^-j, 0 <= j <= N If the book doesn't specify the name of the function, make up a sensible name, like perfsquare for the perfect square function (E6.7). If you finish with enough time, do E6.2, and I'll check your work with you one-on-one.
