 Toolbox provides a ``gold standard" with which to compare new algorithms or even the same algorithms coded
in new languages or executing in new environments.

Secondly, they allow the user to work with real problems, not trivial examples.
For real robots, those with more than two links, or real images with 
millions of pixels the computation is beyond unaided human ability. 
Thirdly, they allow us to gain insight which is otherwise lost in the complexity.
We can rapidly and easily experiment,  play "what i
