Python for Data Analysis, 2nd Edition

多重网格方法求解矩形边界条件下泊松方程，偏微分方程数值求解(use multigrid method to solve poisson equation in rectangular domain)

一维热传导方程的求解，包括显式和隐式，及其对比(One-dimensional heat conduction equations, including explicit and implicit, and the contrast)

幂律分布的数据案例，这个案例数据有助于理解幂律分布的计算公式。(The case of power-law distribution of data, case data will help to understand the power-law distribution formula.)

用三元组表为结构，实现稀疏矩阵的加法并输出。(Achieve sparse matrix addition)

用于有限元软件Abaqus分析材料断裂的粘结区模型（CZM）子程序，由著名学者高彦飞编程，具有很高的参考价值。(ABAQUS allows the addition of a variety of user subroutines. We define a user element by UEL. Information of element and nodal displacements can be obtained from ABAQUS, and we update the stiffness matrix and the residual vector following the cohesive zone law. More coding details can be found in ABAQUS manual.)

最小二乘递推算法及其matlab实现（计算估计值）(least squares method)

使用惩罚函数法对机械设计中的问题进行优化处理(The use of penalty function method for mechanical design optimization problems deal with)

vc++实现编译原理中的LL(1)文法的编译过程,非常好用.(vc realization of the principle of compiler LL (1) grammar compiler course, very handy.)

面元法程序，用于计算飞行器气动力、气动力矩系数。(panel code for aero calculation.)

滤波程序，从同事那里要的，大家一起交流学习(BADNELL & BURGESS D.A.M.T.P. CAMBRIDGE C C DIAGONALIZATION OF REAL SYMMETRIC N-BY-N MATRIX Z.
