MATLAB使用欧拉Euler法求解微分方程组 源程序代码

本人上传的为线性拉东变换方法，它能够提取面波的频散曲线(I uploaded is of linear radon transform method， it can extract of surface wave dispersion curves)

再生混凝土细观损伤分析程序，采用随机骨料模型与双折线模型。(Recycled concrete meso-damage analysis procedures, using random aggregate model with two-line model.)

说明：  用刷选法求出100之内的素数。并输出数有多少个。(100 prime number is calculated by the method of selection. And the output count how many.)

计算各种气象物理量，包括散度、涡度、螺旋度、垂直速度、水汽通量、比湿、假相当位温、k指数等的grads 程序，(Calculate various meteorological physical quantity, including divergence, vorticity, helicity, vertical velocity, water vapor flux, specific humidity, pseudo-equivalent temperature, k index grads program,)

模拟二维BZ反应扩散模型，方法是用显式EULER法求解模型的偏微分方程组(Simulated two-dimensional BZ reaction-diffusion model, the method is to use explicit EULER method for solving partial differential equations model)

利用五点差分格式和Jacobi迭代法，求解精确解和数值解的误差，判断阶数是否正确(Five-point difference scheme and Jacobi iteration method are used to solve the error between exact solution and numerical solution and to judge whether the order is correct or not.)

分维反映了复杂形体占有空间的有效性，它是复杂形体不规则性的量度。它与动力系统的混沌理论交叉结合，相辅相成。它承认世界的局部可能在一定条件下或过程中，在某一方面（形态，结构，信息，功能，时间，能量等）表现出与整体的相似性，它承认空间维数的变化既可以是离散的也可以是连续的，进而拓展了视野。(Fractal dimension reflects the validity of space occupied by complex bodies, which is a measure of irregularity of complex bodies. It combines with chaos theory of dynamic system and complements each other. It recognizes that the part of the world may be similar to the whole in certain conditions or processes (form, structure, information, function, time, energy, etc.). It recognizes that the change of spatial dimension can be discrete or continuous, thus expanding the horizon.)

几个多目标求极值的Matlab算法，包括模式搜索法、Rosenbrock法、单纯形法、Powell法、最速下降法、共轭梯度法、牛顿法、信赖域法(Matlab algorithm, several multi-objective extremum including pattern search method, Rosenbrock method, simplex method, Powell method, the steepest descent method, conjugate gradient method, Newton' s method, trust region method)

快速傅立叶变换，双边傅里叶变换的LabVIEW程序(Fast Fu Liye transform, bilateral Fourier transform of the LabVIEW program)

说明：  隐马尔可夫的经典文献，和通俗易懂的PPT，很好的经典资料，文献常被应用，甚至PPT都经常被模仿(Hidden Markov classic literature, and user-friendly PPT, classic good information, the literature is often applied, or even PPT are often imitate)
