Good question. Like as FFT<>IFFT, also EDFT<>IFFT is a pair of DFTs adequately connecting two domains. Unlike FFT, the EDFT adapts to the frequency domain (see details on site http://arxiv.org/abs/1303.2033) and this leads to data extrapolation. Thus, "Super Resolution" is dictated by the known laws physics, from where the longer data, the higher the resolution. Thanks.

Extended DFT
Program EDFT produce high-resolution N-point DFT for N greater than the length of data vector.

in the function nedft.m I am getting an error:
Undefined function 'finite' for input arguments of type 'double'.
Error in NEDFT (line 119)
if sum(~all(finite(X)))|sum(~all(finite(tk)))|sum(~all(finite(fn))),
Documentation (2012a) says:
Function finite Being Removed
The finite function is obsolete. Use of the finite function now causes an error in MATLAB.
Compatibility Considerations
Replace all instances of finite with isfinite
