有四个单独的MATLAB程序，是对一幅256的单色图像进行最大值计算，最小值计算，均值计算，还有一个是画出其直方图(four separate MATLAB program is to a 256 monochrome image maximum, minimum, mean, there is a painted its histogram)

信号阶谱分析，采用高阶分析处理信号，有效提取阶次信息(Signal order spectrum analysis, higher order analysis is used to process the signal, and the order information is extracted effectively)

Function Approximation using ANN without Toolbox

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!

基于向量内积的相似性K-means聚类算法(Based on vector similarity of inner product K- means clustering algorithm)

这是一个简单的模糊逼近(matlab)源代码，可供参考(This is a simple fuzzy approximation (matlab) source code is available for reference)

地球坐标系ecef坐标与地理坐标系(bj54/wgs84)转换。(Ecef coordinate system and geographic coordinates (bj54/wgs84) conversion.)

说明：  这是黑龙江大学自控理论专业同学在最优估计课程当中用matlab编写的带遗忘因子的最小二乘法!(This is the theory of controlled Heilongjiang University students in professional courses optimal estimate prepared by using Matlab forgotten factor with the least squares method.)
