说明：  GPS接收机方面的MATLAB程序，有很多gps接收机实现时所用到的函数，很很好的参考，快速掌握GPS接收机实现方法(GPS receiver' s MATLAB program, there are many gps receiver when used to achieve the function, it is a good reference, to grasp the realization GPS Receiver)

利用DCT进行图像压缩（首先将图像分割成8×8的图像，对每个子图像进行DCT，这样每个子图像有64个系数，舍去50％小的变换系数，进行2：1的压缩。）(Using DCT for image compression (first image into 8 × 8 image, for each sub-image DCT, so that each sub-image by a factor of 64, rounding 50 of the small transform coefficients, the 2:1 compression.))

基于四级四阶龙格库塔算法的MEMS IMU数据的捷联姿态解算(SINS solve)

This book is about how to make MATLAB-based Graphical User Interface (GUI) tools. It falls naturally into two parts: • GUI design, or how to make something that’s useful • GUI implementation, or how to make something that works The principles of good GUI design are, for the most part, timeless and universal. They apply in MATLAB as much as they apply anywhere else,though we consider them here with respect to specific examples. The guidelines for GUI implementation, on the other hand, tend to be much more specific—many of the implementation details we discuss here weren’t possible in MATLAB until recently. Accordingly, in this manualthere is a trend from the general to the specific. Part of the second half of the manual is devoted to the use of MATLAB’s GUI-building tool, Guide (Graphical User Interface Development Environment). A quick start example of how to use Guide also closes out this introductory chapter.

本文对变步长(VSS) 自适应滤波算法进行了分析,针对输入信号高度相关时算法收敛速度下降导致性能下降 的问题,提出了一种解相关变步长归一化LMS 自适应算法,引入相关性原理,使得算法保持良好的收敛性能。计算机仿真 结果与理论分析相一致(In this paper , we discuss and analyze the variable step2size adaptive algorithm(VSSLMS) ,in which the descent of it s convergence speed leads to the reduction of performance when input signals are heavily correlated . As a result , we propose an uncorrelated variable step2size normalized LMS adaptive algorithm. Due to the principle of correlation ,the algo2 rithm can achieve good performance. The simulations agree to the theoretical analysis.)

matlab code for show image and read the image

在dq坐标系下建立异步电机，并进行启动仿真(In the dq system of asynchronous motor, and start the simulation)

该程序是基于粒子群算法优化支持向量机中的正则化参数C和核函数参数K的算法，实现了对电力负荷的短期预测，预测效果较好，可根据自己要求进行更改。(The algorithm is based on particle swarm optimization algorithm to optimize regularization parameter C and kernel function parameter K in support vector machine. It realizes the short-term prediction of power load, and the prediction effect is good, and can be changed according to the requirements.)

lsb embedding for invisible image watermarking

This MATLAB code generates a square circulant matrix using the vector V as the first row of the result if V is a row vector or as the first column of the result if V is a column vector. V may be any numeric data type or a character string.
