TFD (topological fluid dynamics) matricial form

[banutraul]

Homework Statement

Using the matricial form of TFD (discret Fourier Transform) calculated : X=Fd(x) for x=(1,0,2j,1-j)^T from K^4

Homework Equations

X=wx

The Attempt at a Solution

I know the "x" matrix and the "w" matrix but i don't know how to find the "ω" variable from the "w" matrix. "ω" is referring to variable from the TFD direct formula : Σ f(t) [ω][/-mn] ( n=0,N-1)
