I had a similar problem some time ago,
which i solved by building my own class containing
an n-d array and an n-d interpolator. Then i overrided the __getitem__
special method
so that i could use a fancy notation like the one you want. Inside the
method i used
n-d dimensional interpolation of the nd.array to get function evaluation
at the point/s specified.
Maybe this can help,
