I'm very interested by it too, mostly by interpolation routines. How
does the code you have compare to the "sparse grid interpolation
toolbox" by andreas Klimke ? This one has adaptive dimensions and
several types of grid, but I found it quite slow and not very useful
when repeatedly evaluate an interpolated function.
I also have a piece of code in Python for sparse products of Chebychev
(sorry to send that link again). It is pure vectorized numpy and I'm
curious to see how it would compare (have no doubt it is very memory
