Fast fourier transform (fft)?

Dear all,

Suppose that I have a vector with the numerical solution of a

differential equation -- more concretely, I am working with evolutionary

game theory models, and the solutions are frequencies of types in a

population that follows the replicator dynamics; but this is probably

irrelevant.

Sometimes these solutions are cyclical, yet I sample at points which do

not correspond with the period of the cycle, so that np.allclose()

cannot be directly applied.

Is there any way to check for cycles in this situation?

Thanks for any advice,

Manolo
