% This is a template file for the first assignment to get started with running
|
|
% and publishing code in Matlab. Each problem has its own section (delineated
|
|
% by |%%|) and can be run in isolation by clicking into the particular section
|
|
% and pressing |Ctrl| + |Enter| (evaluate current section).
|
|

|
|
% To generate a pdf for submission in your current directory, use the following
|
|
% three lines of code at the command window:
|
|
%
|
|
% >> options.format = 'pdf'; options.outputDir = pwd; publish('assignment2.m', options)
