很好用的介绍差分方程和数值微分的PPT，希望对大家有帮助，欢迎下载。(Nice introduces difference equation and numerical differential s PPT. We want to help, welcome to download.)

说明：  A*算法实现栅格障碍路径规划matlab代码(A * algorithm for grid obstacle path planning)

optimizatiom multivariate optimization(sr1)

matlab处理地震资料的有关比较简单的成程序，segy文件的读取程序及输出segy格式的程序，另外还有雷克子波的程序等(matlab processing seismic data into a relatively simple procedure, segy file read program output segy formats procedures, in addition Leike Zi wave program)

参加数学建模大赛获奖，提供图像的拼接的matlab源代码，有很大价值(Participate in mathematical modeling contest winners, providing an image stitching matlab source code, there is great value)

说明：  用matlab实现jacobi方法和seidel方法的数值积分的例程(Using MATLAB to realize the routine of Jacobi numerical integration and Seidel numerical integration)

字符串动态显示，可以动态从左至右，也可重复显示，效果极佳(String dynamic display, you can dynamically from left to right, but also repeated showed excellent results)

说明：  实现卡尔曼滤波，可以看出，滤波过程是以不断地“预测—修正”的递推方式进行计算，先进行预测值计算，再根据观测值得到的新信息和kalman 增益（加权项），对预测值进行修正。由滤波值可以得到预测，又由预测可以得到滤波，其滤波和预测相互作用，并不要求存储任何观测数据，可以进行实时处理。(Kalman filtering, can be seen, the filtering process is constantly &quot forecast- Fixed&quot recursive manner calculated to predict the value of the first, and then according to the new information should be observed and the kalman gain (weighted items), on predictive value of the amendment. Value can be predicted by the filter, but also can be filtered by the forecast, and its interaction filtering and prediction, does not require the storage of any observational data, real-time processing.)

说明：  输入信号为谐波信号，用brug算法运算线性模型系数。(Input signal for the harmonic signal, using brug coefficient linear model algorithm.)
