关于计算机模拟的matlab实验(Matlab on the computer simulation experiment)

本文基于BP神经网络应用于预测的原理，提出预测步骤及预测可行性，探讨建立基于BP神经网络的预测模型的关键技术，包括样本的选取与预处理、输入输出变量的选取、隐层节点数的确定、初始权值和阈值的选取、激活函数、训练算法与参数的选取，最后建立合理的网络模型；结合住宅市场的实际情况，建立两类BP 神经网络预测模型：基于时间序列的趋势预测模型以及基于影响因素的回归预测模型，即分别采用神经网络趋势预测和回归预测的思路，把住宅市场的供给、需求与房价的历年数据以及其影响因素的数据分别作为学习样本，建立预测模型，进行预测。(Real estate development risk prediction )

滤波器组的PWVD很不错的我已经试过了很好(filter group Ville very good, I have tried very good)

说明：  在MATLAB平台上通过实验进一步了解离散小波变换，加深对小波变换的理解(Digital watermarking based on Wavelet Transform)

基于元胞自动机的微观交通流建模仿真的结果matlab图形仿真(Graphic simulation of microscopic traffic flow modeling based on cellular automata simulation matlab)

用已有的imf 分量画hht谱图，需要调用InstFreq 函数(Imf components with the existing painting hht spectrum function call InstFreq)

在Matlab中实现了Cordic快速算法，并实现了sin(x), cos(x), atan(y/x), sqrt(x^2+y^2)等函数的快速计算，并附加了误差分析的结果图，代码清晰简洁，对Cordic算法的迭代次数确定，有一定的指导意义(Cordic implemented in Matlab fast algorithm, and realized sin (x), quickly calculate cos (x), atan (y/x), sqrt (x ^ 2+y ^ 2) and other functions, and attach the results of the error analysis Figure, clear concise code, Cordic algorithm for determining the number of iterations, there are certain guiding significance)
