Is this more undocumented Matlab weirdness?  I don't see this behavior in
their documentation (http://www.mathworks.com/help/techdoc/ref/char.html). 
What character did they choose to fill the new character matrix with?

This code snippet should produce a 5x3 matrix and show the integer value of
whatever fill character they used.

double (char (5, 3))
