It is possible to do the same thing directly in C, but as you've found there aren't convenient APIs for this yet.

Dear experts,

is there a C-API function for numpy which implements Python's

multidimensional indexing? Say, I have a 2d-array

PyArrayObject * M;

and an index

int i;

how do I extract the i-th row or column M[i,:] respectively M[:,i]?

I am looking for a function which gives again a PyArrayObject * and

which is a view to M (no copied data; the result should be another

PyArrayObject whose data and strides points to the correct memory

portion of M).

I searched the API documentation, Google and mailing lists for quite a

long time but didn't find anything. Can you help me?

Thanks, Johann
