Re: Create linear spaced vector?

[kjmacken]

Thanks for the code snippets guys.  Exactly what I needed to get going.

I knew I could get the solution from matplotlib, but getting it
installed using Fink (OS X) has been giving me a headache, so I thought
I could just write my own function for now to get a small piece of code
written

The help is greatly appreciated.

John,

Thanks for the heads up RE: scipy, I will keep my eyes on the
developments.

Also, thanks for the info:

that the matplotlib.mlab package (where linspace and others functions
reside) do not require any extension code and can be reused anywhere

I was able to get these modules into my site-packages directory, and
make use of what is there.

Cheers,

kjm
