Commands you will definitely not need to know

These commands behave somewhat unusually:

1. Enter "reshape(1,[-1,1])" at the Matlab prompt once. Then enter it again, and again. Note: "Cleve" = Cleve Moler, founder of Mathworks.
2. Enter "image" with no arguments.
3. Enter "why" at the prompt repeatedly.

The rest listed at www.eeggs.com don't seem to work with more recent releases of Matlab.
