王勖成的《有限单元法》资料包，包括pdf书籍、课后习题答案以及有限元分析教学程序FEATP源码！(The package of finite element method by Wang Xucheng, including pdf books, after-school exercise answers and finite element analysis the teaching programFEATP source!)

用fortran编写的计算水凝胶变形的UEL(Written using fortran calculated deformation of the hydrogel UEL)

matlab语言写的计算八木天线的程序，可以改变单元的数量，给出各个阵子的电流分布和方向图 (matlab language computing Yagi antenna program, you can change the number of units each time around given the current distribution and orientation map)

说明：  matlab调用cplex12.1的例子，这些例子对matlab的cplex接口函数做了非常详细的说明，适用于cplex-matlab的初学者(matlab call cplex12.1 the examples that the cplex interface function of matlab to do a very detailed explanation for beginners cplex-matlab)

毕业设计有用，相控阵天线的方向图（切比雪夫加权），基于matlab GUI界面设计。( Graduation useful Phased array antenna pattern (Chebyshev weights), Based on matlab GUI interface design.)

对平面上给定的多点进行多项式曲线的拟合，可设置拟合多项式的次数(Given more points on the plane polynomial curve fitting, you can set the number of polynomial fitting)

程序计算在声速梯度下水中声线的传播并计算声线的长度(Program calculates the velocity gradient in the water line of acoustic sound propagation and calculate the length of the line)

说明：  同伦连续算法，很好得用来求解非线性方程组(Homotopy continuation method, may very well be used to solve nonlinear equations)

该程序通过编写fortran，得到abaqus之程序usdfld，并实例分析。(The program is by writing fortran, get abaqus procedures usdfld, and case analysis.)

预处理CG算法，在进行共轭梯度法之前先对系数矩阵进行预处理，再进行迭代(pretreatment congruent gradient)
