This is a proof-of-concept implementation of the algorithm introduced in 

Low-rank solvers for fractional differential equations. Tobias Breiten,
Valeria Simoncini, and Martin Stoll, To appear in ETNA, 2016


Please run
setup_fd_3d.m for a 3D space plus time fractional derivative (tensor problem)
setup_fd_coeff.m for a 2D fractional space plus classical time derivative (matrix equation)

1) These codes require the tt_toolbox https://github.com/oseledets/TT-Toolbox
2) The performance of these code can likely be improved by utilizing the qtt_toep objects.  
4) Please rememeber the codes are not perfect and no guarantee is given. Suggestions are welcome at
