根据经度纬度时间，计算太阳的方向角，matlab源码，附有详细的文档注释。(According to longitude latitude time, calculating the direction of the sun angle, matlab source, with detailed documentation of the Notes.)

说明：  用四阶Runge-Kutta法解延迟微分方程组，用到的朋友看一下啊(Using fourth-order Runge-Kutta method for delay differential equations, a friend used to look at ah)

地球科学：重力场积分(Fortran90) Stokes/Hotine/V_M垂线偏差积分：数值积分、二维平面FFT、二维球面FFT、一维FFT(Earth Sciences: Gravity Field Points (Fortran90) Stokes/Hotine/V_M deflection of the vertical integration: numerical integration, the two-dimensional plane FFT-dimensional sphere FFT, one-dimensional FFT)

求人体信号的一个周期序列的CZT和FFT计算结果比较。是很好的程序，可以直观的看到效果。(Order to signal a cycle of the human sequence comparison CZT and FFT calculations. Is a very good program, you can see the visual effect. The body s signals.)

工具箱 (粗糙集数据分析工具箱) matla 中使用 (Kit (Rough Set Data Analysis Toolbox))

用C语言程序通过先随机选取K个对象作为初始的聚类中心。然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。一旦全部对象都被分配了，每个聚类的聚类中心会根据聚类中现有的对象被重新计算。(C Programming Language by first randomly selected the K object as initial cluster centers. And then calculate the distance between each object and each seed cluster center, and assign each object to its nearest cluster center. Cluster centers, and the object assigned to them on behalf of a clustering. Once all the objects are assigned to each cluster cluster centers will be based on the existing object clustering is recalculated.)
