MatLab-7--Creating-Graphical-User-Interfaces

This code permit to simulate the sound received on microphones given their positions, the positions of the sound source(s), the frequency sampling of acquisition and the speed of sound. Assuming anechoical conditions.

MATLAB的PLC仿真与研究文档，非常全！(MATLAB the PLC simulation study of documents, very full!)

基于matlab简单图像处理系统中对图片的取反功能(Based on a simple matlab image processing system for the inversion of the image)

西北工业大学研究生课程，数字信号处理上机作业三(Northwestern Polytechnical University post-graduate courses, digital signal processing, machine operating)

并联机器人运动学计算，包括各个支腿的位移变化，速度变化，加速度变化曲线(Kinematics calculations, including the displacement of each leg, speed change, acceleration curve)

说明：  三角形，四边形 空间体单元等的刚度矩阵的组装，应力求解，有限元分析，该m文件可直接被matlab调用(Assemble the stiffness matrix of triangle, quadrilateral space element, stress solution, finite element analysis, the M file can be directly called by MATLAB)

根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)

灰色关联度分析及灰色预测，本函数是根据GM(1,1)模型所编写而成的，大致思想是： % 对于一些有噪声的数据，通过一次累加生成，使其变为较为有规律性的数据，通过对于该数据的预测从而实现对于原数据的预测。(Grey correlation analysis and grey prediction)

image compression using wavelet using matlab

说明：  利用WS模型的断边重连特性从网络中随机选择边进行断边重连，以此来改变算法的邻域结构，提高算法的多样性。(the model off Bian WS rewiring randomly selected features from the network of conducting an off side reconnection algorithm in order to change the neighborhood structure, increase the diversity algorithm.)
