说明：  三次样条差值—三转角法的仿真，用于数值分析(Cubic spline difference- three corner simulation method for numerical analysis)

三次样条插值函数，可以直接调用，本人亲测过来，用了matlab现成的函数在里面(Matlab cubic spline interpolation function can be called directly)

语音参数提取：短时过零率、短时能量、短时平均幅度、自相关序列、傅里叶分析(Speech parameters extraction: short-time zero-crossing rate, short-time energy, short-term average autocorrelation sequence, Fourier analysis)

I uploaded sample code for SIMPLE-algorithm and solving lid-driven cavity flow test. It has a lot of shortcomings, but I think that it will be useful for all newcomers. I intend to develop it further, but now it very slowly converges. All notes will be useful, and hope it can be discussed.

遗传算法matlab程序，步骤为设置最大迭代步数、计算当前最大的适应度、设置初始取值范围[0 255]、进入加速迭代的间隔、选择交叉、变异等(Genetic algorithm matlab program, the steps to set the maximum number of iterative steps to calculate the current maximum of fitness, set the initial range [0 255], into the accelerated iteration interval, choose the crossover and mutation)

matlab 代码，利用分步傅里叶方法求解NLSE方程(matlab code, solve the equation NLSE)

特征线法（中矩形公式）数值模拟一维不可压缩瞬变流动(Characteristic line method (in the rectangle formula) one-dimensional numerical simulation of transient flow of incompressible)

说明：  （蒙特卡洛方法） 求出四分之一圆占正方形的比例。随机投点P(x,y)于正方形，π/4的近似值为落在四分之一圆内的点数与总投点数的比值。随机投点次数分别为10000次和50000次，计算π的近似值。 ((Monte Carlo method) are obtained accounting for a quarter of a round square ratio. Voted random point P (x, y) in the square, π/4 for the fall quarter of the approximation of the points won and the ratio of the total vote points. The number of random points, respectively, voted for the 10000 and 50000 times, the calculation of the approximation of π.)
