Fortran-Programs

同伦方程组求非线性方程组所有解，自编程序，很好用(Homotopy equations for all solutions of nonlinear equations, written procedures, very good use)

说明：  有两个ARMA过程，其中信号1是宽带信号，信号2是窄带信号，分别用AR谱估计算法、ARMA谱估计算法和周期图法估计其功率谱。(There are two ARMA processes, in which signal 1 is a wideband signal and signal 2 is a narrowband signal. The power spectrum is estimated by AR spectrum estimation algorithm, ARMA spectrum estimation algorithm and periodogram method respectively.)

单纯形法找初始可行解，上课留的作业，希望对别人有点用吧(Simplex method to find an initial feasible solution , hope it is useful for others.)

program array 1 dimensi

有限体积法计算二维方腔流（含数值算法介绍及C++，Fortran源代码）(Calculation of two-dimensional cavity flow with finite volume method (including introduction of numerical algorithm and C++, Fortran source code))

fft变换后求出主频，FFT transform to calculate frequency

FFT（Fast Fourier Transformation）是离散傅氏变换（DFT）的快速算法 [1] 。即为快速傅氏变换。它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。(FFT (Fast Fourier Transform) is a fast algorithm of discrete Fourier Transform (DFT). That is fast Fourier transform. According to the odd, even, imaginary and real characteristics of discrete Fourier transform, the algorithm of discrete Fourier transform is improved.)

说明：  包含马尔可夫预测、贝叶斯决策、模糊聚类分析、模糊综合评价方法等多种计算方法(Including Markov prediction, Bayesian decision-making, fuzzy clustering analysis, fuzzy comprehensive evaluation and other calculation methods)

北京航空航天大学数值分析大作业第二题，有难度，这可是历年北航研究生转载最多的代码了(Beijing University of Aeronautics and Astronautics numerical analysis of large operating the second question, there is difficulty, this is the most over the years Beihang University Graduate reproduced the code)

用于计算stewart 六自由度运动平台的正解问题(this program is designed for stewart platform。)
