I think that there's a bug in the test cases; putting
clear V1;
before test case 7 should fix it.

James on 8 Jul 2013

clear V1 has now been added before test case 7, and the solutions are being rescored. Hopefully, this will fix the problems you were having.

William on 10 May 2019

I have a solution that solves all of the test cases, but when I run it against the test suite it produces "Error using builtin
Undefined function or variable 'solutionTest'." for each case.

Karl Ezra Pilario on 12 May 2020

I have the same problem as William. Can someone help?

Apparently James is deleting essential files for Cody by using rm at his script. I've informed him of the issue.

I have commented out the initial lines so that this problem is solvable again.

Rafael S.T. Vieira on 29 Sep 2020

Thanks, goc3.
