基于遗传算法BP网络预测，代码没有使用遗传工具箱，而是根据遗传算法理论进行编程，有助于理解遗传算法原理(BP network prediction based on genetic algorithm, the code does not use genetic toolbox, but according to the theory of programming genetic algorithms, help to understand the principles of genetic algorithms)

递推极大似然估计法参数辨识的MATLAB源码(Recursive maximum likelihood estimation MATLAB source parameter identification)

程序为MATLAB编写的精馏塔静态模拟程序，包括泡点计算，活度系数计算等(Program written in MATLAB for the static simulation distillation process, including bubble point calculation, calculation of activity coefficients)

Wind energy model. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.

matlab工具箱函数汇总,方便查询各个函数的用途。(Summary toolbox matlab function to facilitate the use of inquiry in all functions. )

创建一个高斯分布并画出其PDF曲线，文件设置为均值为0.其分散为1，参数可以调节(Create a Gaussian distribution, and Draw the PDF curve, the file is set to mean 0. The spread is 1, the parameter can be adjusted)

灰度图像阈值分割，用二维otsu方法实现的matlab程序(Gray image threshold segmentation, using two-dimensional Otsu method of matlab program)

avi格式文件转换为图片文件。该文件可以自行选择bmp或jpg格式，然后将avi视频的每一帧转换为相应格式的图片。(this program can convert the frames of the avi objects to pictures.)

欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)
