SEGMENT

说明：  基于L*a*b空间的色彩分割。根据样本区域的颜色对图像进行分割。(based on the l*a*b space to cut the picture)

星历数据读取文件，用来读取GPS获得的星历数据，以便计算。(Star calendar data reading files, to read the GPS get star calendar data, for the calculation.)

说明：  单个脉冲序列生成子程序 & 用脉冲响应不变法把模拟滤波器系数变换为数字滤波器系数的函数 (single pulse sequence generated subroutine)

代码——Matlab 如何截取视频中的每一帧图像并保存(Code- Matlab how to intercept each frame in the video image and save)

数值积分MATLAB代码，包含4种数值积分方法，分别为复化梯形、复化抛物线、梯形逐次分半、抛物线逐次分半。且编写采用向量化思维效率高、代码简洁。(Numerical integration MATLAB code, including four kinds of numerical integration methods are Trapezoidal, Compound Parabola trapezoid successive half parabolic successive half. And prepared to quantify the use of high-efficiency thinking, concise code.)

mathworks也提供Curve Fitting Toolbox，不过要钱，这是一个一维Curve Fitting的工具包，提供命令行和GUI接口。(MathWorks also offers Curve Fitting Toolbox, but for money, this is a one-dimensional Curve Fitting tool kit, providing the command line and GUI interface.)

The remarkable advance in hydraulic and electrohydraulic power systems resulted in producing control valves of very short settling time. The rapid closure of hydraulic transmission lines leads to severe pressure surge. Thattached Simulink file is developed to evaluate the applicability of oleo-pneumatic accumulators for the protection against this phenomenon. A lumped parameter model was developed for the transmission line, assuming four lumps, considering the effect of line resistance, inertia and capacitance.

说明：  实现画一个六边形，再均匀撒一些点，在六边形内部的点为红色，在外部的点为蓝色(six point point)

利用该代码可进行非线性光学材料的闭孔Z扫描曲线拟合，给出材料的三阶非线性光学极化率(theoretical to closed aperture Z scan)
