混沌0-1检验方法程序 % Z1TEST Gottwald-Melbourne 0-1 test for chaos % Z1TEST(X) is the result of the 0-1 test applied to the vector X. % Result is near to 0 for non-chaotic data and near 1 for chaotic data. % see http://arxiv.org/pdf/0906.1418v1. Paul Matthew

FFTW is a free collection of fast C routines for computing the Discrete Fourier Transform in one or more dimensions. It includes complex, real, symmetric, and parallel transforms, and can handle arbitrary array sizes efficiently. FFTW is typical
