Purpose This is a brief tutorial on Matlab to help you get started. Matlab has a number of core deficiencies, but the most severe for our purposes is that addressing of arrays in Matlab follows the ones-based indexing convention of an ancient programming language, FORTAN, meaning that the first element of an array, s, is s(1), not s(0), as it would be in C, C++, Java or other modern languages with zero-based indexing. In your assignment, you'll use Matlabs object-oriented programming language to create a sequence class that solves this problem. Purpose This is a brief tutorial on Matlab to help you get started.
