What matlab command, or combination of commands (using 25 characters or less), could be used to create the following matrix?

1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0

1 1 0 0 0 1 1 0 0 0 1 1 0 0 0 1 1 0 0 0

Hint: Look for a lower triangluar matrix that is repeated many times. First try to produce that lower triangular matrix with as few characters as possible.

I miss Matt Figs the hump-day puzzlers. The assessment method of Cody collide with my personal opinion about nice and efficient code.

Yes, I never go near Cody personally since I found that 'best' solutions to many problems involve some ridiculous use of regexp. Personally my idea of good code doesn't involve using the fewest characters possible!
