test_tlder.p -- In Homework #10a you are required to write the MATLAB function tlder() which builds derivative matrices across a staggered 2D grid. This MATLAB program test_tlder.p calls your tlder() function hundreds of times with different input arguments to test all of the features.
stlder.p -- This works just like tlder(), but it only generates derivative matrices for small grids. It is provided to help you troubleshoot your tlder() function by providing correct answers.
hw10a_checker.p -- This function checks the output of your code for Homework 10a. Install it in your working MATLAB directory. Run your code and then run this.
Note: The above items are protected function files and have a ".p" extension. They work just like ".m" files, but they cannot be opened to view the code inside them.
