a software code for computing selected eigenvalues of large sparse symmetric matrices

1）先利用文件Lorenz.m求解出Lorenz系统，并把其数组保存成名字为un.mat的文件。 2）直接运行文件Lorenz1.m 便可统计出Lorenz系统的轨道(a) first use of document Lorenz.m solved Lorenz system, and the preservation of its array of un.mat name into the paper. 2) Run the file directly Lorenz1.m Lorenz will be the statistics on the track)

说明：  多目标粒子群算法，求解多目标问题的经典的算法之一(multi-object PSO, one of the classical algorithms for solving multi-objective problems)

基于FFT的伪码捕获，并且非相关累加使之工作在更低信噪比条件下。(FFT-based pseudo-code acquisition, and non-work related cumulative so that at lower SNR.)

This is a Hybrid PSO GSA Aigorithm.A new hybrid population-based algorithm (PSOGSA) is proposed with the combination of Particle Swarm Optimization (PSO) and Gravitational Search Algorithm (GSA). The main idea is to integrate the ability of exploitation in PSO with the ability of exploration in GSA to synthesize both algorithms’ strength. Some benchmark test functions are used to compare the hybrid algorithm with both the standard PSO and GSA algorithms in evolving best solution.

说明：  一个用Matlab编写的的俄罗斯方块程序。(a prepared using Matlab Russian squares procedure.)

单脉冲和差波束测角程序。 此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖(Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan)

故障信号的采样值，采样频率为100KHZ(Fault signal samples, the sampling frequency is 100KHZ)

《MATLAB实用教程---控制系统仿真及应用》的配套光盘，不但便于读者使用，而且给任课老师提供了生成数量不限的练习题的功能，便于因人施教。希望对大家有帮助(" MATLAB practical tutorial--- Control System Simulation and Application" matching discs, not only to facilitate the reader to use, but are not limited to the classroom teacher provides a number of functions to generate exercises, to facilitate individualized instruction. I hope everyone has to help)
