I have posted my example (using the current interface) at http://www.scipy.org/ConjugateGradientExample
. I have also added a link to it from Alan's http://www.scipy.org/MatrixIndexing
so that they will be somewhat connected.
It is just one example, and provides one small area where the vector
classes would be useful. I hope others will post similar examples, so
that the design discussion can address concrete, agreed-upon situations.
Note that I started using "row_vector" and "col_vector" as the class
names in my discussion. No reason to re-introduce camel-case to
numpy, and I think "col" is a universally recognized abbreviation for
"column" and I like the symmetry of the three-letter "row_" and "col_"
prefixes.
