I like to be outside. But if I'm inside, I like to be using MATLAB.

I'm an Application Engineer at MathWorks and civil/structural engineer by education.

Some Interests:
-Image Processing, specifically 3d images (CT, mri)
-All things graphics
-Optimization: both of code and objective functions
-Finite Element Analysis

The two things I want to improve on most are regular expressions and OOP.
Professional Interests: MATLAB

I think the test suite is wrong:
If "G" is supposed to have a "minimal number of empty cells" then why is the second test a 9x9 with the last column being all zeros? I would expect this column to be unnecessary.
For the first test, I'm getting 1.2690e-05 for chk2.
Problem is great though!
