导航解算，主要用于姿态的求解，主要利用的是四元数方法(Navigation solvers, mainly for solving attitude, the main use of the quaternion method)

说明：  无线通信中的天线仿真，matlab平台上提供源码，第二部分(Wireless communication antenna simulation, matlab source platform, Part II)

该源码是基于划分的模糊聚类算法，matlab带有自己的fcm算法，此次上传的算法是自己编写的(The source is divided based on fuzzy clustering algorithm, matlab with its own fcm algorithm, the upload algorithm is written in their own)

实现两个稀疏矩阵相乘(效率高于早期的Matlab自带的程序)，Matlab编程 (SSMULT is a simple stand-alone MATLAB mexFunction that computes C=A*B where both A and B are sparse. It is typically faster and always uses less memory than C=A*B in MATLAB 7.4 (or earlier). Works on MATLAB 6.1 to the current version. Untested on earlier versions of MATLAB. It is a built-in function in MATLAB 7.6 and later for C=A*B when both A and B are sparse. )

The mean hydration of carbohydrates as studied by normalized 2-D radial pair distributions, Claus A. Andersson and Sø ren B. Engelsen, Journal of Molecular Graphics and Modeling.The routine takes as input the location of the centerpoint of the two spheres and the two said spheres radii and calculates the rotational common volume used for normalizing the density maps of the atoms under investigation.
