my_fft

Eigenvalues and eigenvectors of a symmetric matrix.

《卡尔曼滤波与组合导航》一书中非线性滤波章节的知识，EKF,UKF,UPF,PF各算法流程比较详细(the flow of EKF,UKF,UPF,PF)

在matlab实现直线插补仿真，对观察插补原理有良好的效果。(In matlab linear interpolation simulation，To observe interpolation theory has a good effect)

说明：  这是一个关于基本的最小二乘的程序，只用Matlab语言编写的。(This is a basic program about least squares, written in Matlab language.)

用HOUGH检测直线的时候是两个未知量,因为轴半径和相角可以确定一条直 线，在HOUGH域出现累计最大点就可能是原域中的直线。现在回到圆的检测 上来，确定一个圆需要什么：X坐标，Y坐标，半径三个未知量吧，好了，现在， 你做一个三维空间的HOUGH域，以这三个未知量作为三个轴，现在按照一定步长 进行三重循环，在最内层循环是这样的，X,Y 确定，以不同的半径进行搜索，如 果你的X,Y刚好就是实际图像的X,Y处，半径又搜索到实际真实的半径(The HOUGH detect straight when two unknown amount of axis radius and phase angle can be determined in a straight line, in the HOUGH domain cumulative maximum point may be the straight line of the original domain. Now back to the circle detection up to determine what a circle: X coordinate, Y coordinate, radius three unknowns, now, you do the HOUGH domain of a three-dimensional space, three to three unknown quantity as axis, in accordance with a certain step size triple loop, is such that in the innermost loop, X, and Y determined search for a different radius, If you X, Y, exactly is the actual image of the X, Y, at the radius radius of the search to the actual real)

此程序为发表过的一篇IEEE PIMRC 的paper的程序代码。是关于异构无线网络环境下的垂直切换接口激活时间的几个方案的仿真性能比较。(This RAR package contains a set of program code which was used in a published paper on in IEEE PIMRC. It is about the interface activition time in heterogeneous wireless networks. )

t3 is a program to show machine learning in matlab

说明：  运用小波包分解功能对含噪信号降噪，剔除干扰噪声，提高信号信噪比。(The function of wavelet packet decomposition is used to denoise the noisy signal, eliminate the interference noise and improve the signal-to-noise ratio.)

音频信号的谱分析及去噪 是一个课程设计的题目 报告很完整 可以使用(Spectrum analysis and audio signal de-noising is the subject of a course design is very complete report can be used)

说明：  结构分析中的有限元法利用matlab实现的教材(Structural analysis of the finite element method using matlab implementation of teaching materials)
