Well, if you're content

Well, if you're content with a 1-D array and speed isn't a big issue,
you can just copy the elements of your array into a Python list like
this:

If you can build a wrapper function which returns a
boost::numeric::ublas::vector, you can use the wrappers into
the mds-utils library (http://code.google.com/p/mds-utils/ ... it's
my library). If you build the doxygen documentation, you'll find a
"Python C++ extensions utilities": use the "vecto

I have C code similar to the following:
float image_data[IMAGE_SIZE];
const float *get_data()
get_data returns a pointer to image_data. I'd like to expose get_data to
python and have it return a copy of the array in some Python type. (it is
actually a 2D array of image data)
In the wrapper
