Description

Hi @dlfivefifty

Firstly, thanks for ApproxFun. :) !!

I wanted to translate a Burger's equation solver from chebfun to ApproxFun. Could you point me to the equivalent of spinop in ApproxFun, if it exists. Or more generally the way to achieve the following:

function u = Burgers(init, tspan, s, visc)

S = spinop([0 1], tspan);

S.lin = @(u) + visc*diff(u,2);
S.nonlin = @(u) - 0.5*diff(u.^2);
S.init = init;
u = spin(S,s,1e-4,'plot','off'); 

Thanks,

Research direction

The issue names no file, test, or entry point. Start by checking ApproxFun.jl's available interfaces for time-dependent PDEs and whether they provide an equivalent to Chebfun's spinop and spin for the shown Burgers solver. Done means identifying a supported approach or documenting that no equivalent exists.
