Obtaining momentum distibution from Green's functions
How does one obtain the momentum distribution (n_k) from the green functions Is there a software for it if so where can I get it

Momentum of what, in which system and under what conditions?
Does this help?

I am working on electron correlation in an 8 X8(64 site) square lattice at half filling using the 2-D Hubbard model. using quantum monte Carlo I was able to obtain the Green functions. To get the momentum distribution I am required to calculate the Fourier transform of the Green function. The problem is I do not know how to go about calculating the Green functions and plotting it. Can it be done with Matlab?
