What is the correct order to put into ifft MATLAB

I am having some trouble with Matlab's FFT and IFFT implementations. My end goal is to be able to numerically construct a function in spectral space (F(k,z)) and then use IFFT to take the result back to physical space with proper scaling (f(x,z)) when it is known that f(x,z) is a purely real function.

How to use IFFT function in matlab? Yahoo Answers

But whatever the factors in front of fft and ifft, if their product equals one then doing g = ifft(a) and going back with a = fft(g) is sure to give you what you started with. ** Since Matlab cannot use 0 for an index, everything ends up being shifted over by one, but the basic idea is correct.
