Matlab Easter Egg - Funny Reshape (R11)

The reshape function only works with positive size arguments. However, if you try it with negative size arguments, you do not get your typical boring MATLAB error message. You even get three different answers !

First try:
» reshape(1, [-1 -1])
??? Error using ==> reshape
Don't do this again!.

Comment: MATLAB seems shocked you request such an operation !

Second try:
» reshape(1, [-1 -2])
??? Error using ==> reshape
Cleve says you should be doing something more useful.

Comment: Nice advice from Cleve Moler, cofounder of the Mathworks.

Third try and following:
» reshape(1, [-1 -3])
??? Error using ==> reshape
Seriously, size argument cannot be negative.

Comment: OK, let's be serious and get back to work now.
