矩阵按键程序，用的是C。本人还是学生，做得不好请大家多多指教(Matrix button procedure is used in C. I am still a student, doing a lot of bad advice please)

理想流体势流的有限元求解程序,简单易懂，适合初学者对该方法编程的一个初步认识,程序内有详细的注释(Potential flow of ideal fluid finite element solver, easy to understand, this method is suitable for beginners programming a preliminary understanding of the program with detailed notes)

说明：  本程序是matlab编写的imm（交互式多模型算法）目标跟踪程序。这种方法的特点是在各模型之间“转换”，自动调节滤波带宽，和适合机动目标的跟踪。(This program is matlab written imm (interacting multiple model algorithm) target tracking program. This method is characterized among the various models &quot conversion&quot , automatically adjust filter bandwidth, and suitable for maneuvering target tracking.)

matlab 程序 圆锥拟合 使用最小二乘法(matlab cone fitting procedure using the least squares method)

根据试试数据 对变压器技术参数进行校核 利用的是最小二乘曲线拟合的方法(According to the data to try check technical parameters of the transformer is the least squares curve fitting using the method)

用matlab对偶极子电场线描绘，能够和等势线一起画出。改变电荷量就能得到不同的电场线分布。(Electric field line of a diple)

说明：  umat abaqus plasticity

基于Python编写的差分进化原理的带边界条件约束算法(A band constraint algorithm based on differential evolution algorithm)

这是四阶的龙格库塔算法和lyapunov指数稳定性。(tihs is a runge kutta method )

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)
