TIDAL-PREDICTION-PROGRAM

附件中是我用Fortran写的lorenz混沌吸引子的lyapunov指数谱产生程序。包括三部分内容：如何产生lorenz吸引子，详细注释，如何计算lyapunov指数谱。 需要的话也可以单独提取子程序中的四阶龙格库塔算法。 希望有所用。(Annex is written in Fortran I used the Lorenz chaotic attractor of lyapunov index spectrum generation process. Includes three parts: how to generate Lorenz attractor, detailed notes, how to calculate the spectrum lyapunov index. If necessary, extraction can also be a separate subroutine in the fourth-order Runge-Kutta algorithm. Would like to see used.)
