非定常导热，附件包含3个源代码。分别对应着FTCE、BTCS和紧致格式的程序代码(unsteady conduction)

用MATLAB编写的遗传算法路径规划，可以提取一幅图中想要的目标，matlab开发工具箱中的支持向量机。( Genetic algorithms using MATLAB path planning, Target can be extracted in a picture you want, matlab development toolbox support vector machine.)

用于计算锁模激光腔中增益饱和强度，用于锁模激光(For calculating the gain saturation intensity in a mode-locked laser cavity for a mode locke)

在有限元分析中的网格划分好坏直接关系到模型计算的准确性，这里是关于网格划分的一些讨论。(In in the analysis of finite element mesh is directly related to the accuracy of the calculation model, there is some discussion about grid division.)

最小二乘拟合的matlab程序，用于数据处理。简单，易懂(The least squares fitting matlab program for data processing.Simple, easy to understand)

说明：  数值分析实验1.明确插值多项式和分段插值多项式各自的优缺点； 编程实现拉格朗日插值算法，分析实验结果体会高次插值产生的龙格现象；(Experiments of numerical analysis 1. Define the advantages and disadvantages of interpolation polynomials and piecewise interpolation polynomials. The Lagrange interpolation algorithm is programmed, and the Runge phenomenon produced by high-order interpolation is analyzed.)

说明：  输入任意数学四则运算表达式可以得出结果,很方便很实用的一个程序的源代码。(you can get the answer.)

说明：  经典99行拓扑优化程序，采用Heaviside方程获得接近0-1离散解(The classical 99-line topology optimization program uses Heaviside equation to obtain nearly 0-1 discrete solution)

说明：  布谷鸟多目标算法用来函数寻优，本代码给出了通用版本，能够很好的适应和学习(CS algorithm used to function optimization, this code gives a general version, can adapt and learn well)

说明：  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.)
