Hi Erik,
3D/4D is in the eventual plan: I really want to be able to solve PDEs
on cylinders/spheres/cubes. Representing functions as tensor product of
coefficients should be straightforward.For low rank approximation a la

I notice that ApproxFun handles 1D and 2D domains. Do you plan to
extend it to 3D or 4D as well? Would that be complicated? If so, is
this about software engineering, or about the numerical analysis
behind the package?

This is to announce a new version of ApproxFun
(https://github.com/dlfivefifty/ApproxFun.jl), a package for approximating
functions. The biggest new feature is support for PDE solving. The
following lines solve Helmholtz equation u_xx + u_yy + 100 u = 0 with the
solution held to be one on th
