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.)

用python写的牛顿迭代法和牛顿插值法，数值分析的实验(Newton iteration method and Newton interpolation method written in Python, numerical analysis experiment.)

说明：  some article about Bayes Thinking

说明：  用于求解耦合速率方程的四阶龙格－库塔数值解法(4th order Runge-kutta methods for solving the coupled rate equations)

罚函数法 它将有约束最优化问题转化为求解无约束最优化问题: 其中M为足够大的正数, 起"惩罚"作用, 称之为罚因子, F(x, M )称为罚函数.(hunhefahanshufa)

典型的二维kalman滤波原理程序，容易掌握！(typical two-dimensional Kalman filtering process easy!)

说明：  任意给定一个M进制的数X，利用栈实现数值转换。(Given an arbitrary number of M band X, use the stack to achieve numerical conversion.)

在第一个图像中的每个描述符，选择它的匹配到第二个图像。(For efficiency in MATLAB, calculating dot multiplication between unit vectors is faster than Euclidean distance. Please note that: The ratio of attention to angle (the cosine of dot product of unit vector) is the approximate value of the ratio of Euclidean distance of small angle.)

空间目标识别，采用PM算法，线性调频脉冲压缩的Matlab程序,多抽样率信号处理。( Space target recognition algorithm using PM, LFM pulse compression of the Matlab program, Multirate signal processing.)

说明：  阵列存在幅相误差条件下的DOA估计算法仿真(Simulation of DOA estimation algorithm with amplitude and phase errors in array)
