Rossker系统设计庞加莱截面，得到参数c的分叉图。把程序function改一下编程Lorenz系统即可(The Poincare cross section of Rossker system is designed and the bifurcation diagram of parameter C is obtained. Change the program function to programming Lorenz system)

说明：   FFTD(T) performs a "Dimensionless DFT" on the columns of T. T may be real or complex. T may be any size. Returns the dimensionless (unitless) vector D and the universal Basis matrix B such that
