ofdm系统信道估计，基于LS,LMMSE,LRMMSE等准侧。是学习的好工具。(ofdm channel estimation system, based on LS, LMMSE, LRMMSE other potential side. Is a good tool for learning.)

利用KNN最近邻算法，对心音信号进行分割并判断，给出第一心音、第二心音和收缩期、舒张期。(Use KNN nearest neighbor algorithm, the heart sound signal is divided and judgment is given first, second heart sound and systolic, diastolic.)

KalmanFilter卡尔曼滤波器最好的介绍(the best intruduction of KalmaFilter)

matlab正交频分复用(OFDM)技术matlab实现仿真源代码(matlab orthogonal frequency division multiplexing (OFDM) technology to achieve simulation source code matlab)

无约束优化,基于黄金分割的最速下降法极小化函数(Unconstrained optimization, based on the steepest descent method minimization function)

This is a kalman filter arithmetic using Matlab. A small example of insipid kalman filtering, and relatively foundation, can help beginners, combining with example study.

Image Filters for Noise Reduction in Images

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)

给定地理坐标（经度、纬度），求出一年中每一天的太阳高度角和方位角(Given geographic coordinates (latitude and longitude), each day of the year, the sun s elevation angle and azimuth angle)
