13中粒子群优化算法

用自适应法做时延估计，然后根据时延估计确定声源的定位(Adaptive time delay estimation method used to do, and then determine the time delay estimation based on the positioning of the sound source)

扩展卡尔曼滤波算法的matlab，很好用的(malman ，it is very good 。)

一，二，三次拟合，并得到R方的检验。输入任何矩阵，得出险要的值。(One, two, three fitting and get R-square test. Enter any matrix derived advantageous values.)

说明：  工程数值计算大气动力学模型的洛仑兹方程工程案例。 计算原理，流程图，程序代码，绘图结果。(Engineering case of Lorentz equation for engineering numerical calculation of atmospheric dynamics model. Calculation principle, flow chart, program code, drawing results.)

montecarlo的源程序，希望对大家游泳 (Montecarlo source, in the hope that U.S. Swimming)

MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式，并编写输出程序用以输出节点导纳矩阵、节点电压（包括电压的相角和幅值）、以及各支路的首端功率、末端功率和功率损耗(MATLAB implementation of the system flow calculation. MATLAB programming language requires the formation of the node admittance matrix, Jacobian matrix formed by modified Gaussian elimination method for solving equations, and write out procedures for the admittance matrix of the output node, the node voltage (including the voltage phase angle and amplitude), and the first end of each branch of power, end power and power loss)

assigning complex numbers

For the 3d implementations, the source files for the in-core version are in the directory fdct3d

本文件提供了雷达系统分析与设计一书配套的全部仿真代码，方便读者对于该书籍的进一步学习。(This document provides radar system analysis and design of a book supporting the whole simulation code, the convenience of the reader for further learning of the books.)

数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。 (Digital modulation is the spectrum shifting to high frequency digital baseband signals, suitable for the formation of bandpass signal transmission in the channel. Digital modulation basic amplitude keying (ASK), frequency shift keying (FSK), the absolute phase shift keying (PSK), relative (differential) phase shift keying (DPSK). At the receiving end can be used to dry the demodulation or non coherent demodulating the digital baseband signal. )
