[Numpy-discussion] dimensions of zero length

Hi all,

I noticed that in Numeric and in numarray it is possible to create arrays with 
axes of zero length. For instance: zeros([1, 0]). There seems not be much
that can be done with them. What is the reason for their existence? 

My real question is: When writing an extension in C, how to deal with such 
arrays? Should I treat them as empty arrays, that do not have any data?

Cheers, Peter
