Determine the rank of a matrix without using the MATLAB function of the same name.
I think the test suite needs to be expanded to include a matrix whose rank does not equal the number of rows. The solution here passes the test suite, but would not actually find the rank.
Sort a list of complex numbers based on far they are from the origin.

Copy/paste rank.m (with a slight tweak since nargin=1) works just fine. :-)
Is it so? Thanks for your input. I will take care next time.
