[Tutor] Unity matrix

[Stuart Murdock]

Hi python dudes,

Does anyone know if there is a builtin to numarray (or an add on ) to 
give me a unity matrix. It would look better than
trying to add ones along the diagonal of a zeros.

I want something like

A = unity((2))

to produce the same as

A = array([[1 0],[0,1]])

Thanks

Stuart
