基于粒子群优化的最小二乘支持向量机的电力系统短期负荷预测的matlab仿真程序。(Matlab simulation program for short-term load forecasting of power system based on particle swarm optimization (PSO).)

LBG算法，初始码本随机给出，然后根据对训练矢量的划分，计算形心，更新码本。原代码中含有去空胞腔的程序。(LBG algorithm, given a random initial codebook, and then based on the division of the training vector, computing the centroid, update this code. Contains the original code to empty cell process.)

這是完整的HHT程序，包括EMD和希爾伯特轉換，非常有用。(This is the complete HHT procedures, including the EMD and Hilbert transform, very useful.)

。本书首先讲述了MATLAB语言程序设计基础，然后分别介绍了符号计算在微积分和复变函数两门大学数学基础课程中的应用，接着系统的介绍了线性方程组、非线性方程与最优化方法、特征值与特征向量、插值与函数逼近、估计方法和数据拟合、积分计算、常微分方程的数值方法。从实用角度考虑，本书许多章节都给出了一些数值分析的应用范例，并在最后一章单独介绍了一些综合性较强的数学建模问题(This book starts by describing the basis of MATLAB programming language, and then introduced the symbolic computation in calculus and complex functions based on two college courses in applied mathematics, and then introduced the system of linear equations, nonlinear equations with the most optimization method, eigenvalue and eigenvector, Interpolation and function approximation, estimation and data fitting, integral calculation, numerical methods for ordinary differential equations. From a practical point of view, many of the chapters the book gives some numerical analysis are examples of the application, and separate in the final chapter describes some of the more integrated mathematical modeling)
