PSO算法优化BP神经网络，数学建模模拟退火算法的改进(PSO algorithm to optimize the BP neural network, mathematical modeling simulated annealing algorithm improve)

MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral / staggered A-B method, including attenuation modeled with two relaxation mechanisms. This example demonstrates harmonic generation within a plane wave given a B/A parameter of 5.2. To increase the distance of propagation, scale the sample grid (num_axpts) by a factor(s) of 2.( MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral /staggered A-B method, including attenuation modeled with two relaxation mechanisms.

本程序为三维FDTD方法在Matlab中的实现。(This procedure for the three-dimensional FDTD method in the realization of Matlab.)

The file lib_crc.c contains source code for functions to calculate five commonly used CRC values: CRC-16, CRC-32, CRC-DNP, CRC-SICK, CRC-Kermit and CRC-CCITT. The functions can be freely used.

how to find a suitable formulation about a plot we can use fiiting tools in matlab this file is a example of my work

说明：  hallen equation :this equation is modeled as matrix equation (the voltage is equal two the current multiplied by resistance),the object is to find the current distribution.

二进制通信系统的进行蒙特卡罗仿真程序，以正交信号为基础。当均值分别等于０，０.１，１.０，２．０时完成１００００个比特的仿真并求出误差概率。绘出理论误码率和蒙特拉罗仿真的差错率并进行比较这俩个结果，并绘出每个均值情况下判决器的１０００个接受信噪比抽样(Binary communication systems to carry out Monte-Carlo simulation procedures to orthogonal signal basis. When the mean, respectively, equivalent to 10,000 completed 0,0.1,1.0,2.0 bit error probability simulation and obtained.
