Genetic Algorithm for Matlab

说明：  基于PCA人脸识别算法的研究，用matlab实现。(PCA-based face recognition algorithm using matlab to achieve.)

有限差分方法（网格法）是最早使用的一种电磁场数 值计算方法。 边值问题 物理思想：场域离散。 （连续区域→网格和节点） 数学基础：差分原理。 （微商→差商） 线性代数方程组 §6-3 有限差分方法 作为数值计算方法，有限差分法将连续场域的问题变换 为离散系统的问题（连续场域划分为若干个细小的区域：网 格和节点）。也就是说通过离散化模型上各离散点的数值解 来逼近连续场域内的真实解。(The finite difference method (grid method) is the earliest use of an electromagnetic field the number of Value method. Boundary Value Problems Physical idea: the field of discrete. (Contiguous area → grid nodes) Mathematical foundations: the difference principle. (The Derivative → difference quotient) Linear algebraic equations. § 6-3 Finite Difference Method Numerical methods, finite difference method will transform the problem of the continuous field For discrete systems (continuous field is divided into several small areas: network Grid nodes). That is, the value of the discrete points in the discrete model solution To approximate the true solution of the continuous field domain.)

在对一组离散数据点进行拟合时，我们采用最小距离拟合来达到拟合的函数与原数据达到最优拟合(In a group of discrete data points to fit, we use minimum distance fit to achieve the fit function to achieve optimal fit with the original data )

通过引力搜索算法，进行支持向量机参数优化。实现模式识别和趋势预测。(The parameters of support vector machine are optimized by gravitational search algorithm. Realize pattern recognition and trend prediction.)
