隐式及显示技术模拟复合材料结构的固化，UMAT程序(Cure Simulation of Composite Structures Applying Implicit and Explicit FE Techniques)

基于matlab计算流体力学(CFD)源代码。(Matlab-based computational fluid dynamics (CFD) code.)

说明：  一个薄板样条模型（thin plate spline）matlab源代码(A thin plate spline model (thin plate spline) matlab source code)

fortran编写的共轭梯度法模块，直接套用，可以直接读矩阵文件(the conjugate gradient method of fortran written modules, ready-made, you can directly read the matrix file)

用SVD奇异值分解法和阻尼最小二乘算法解决地球物理反问题，程序比较简单易懂(Using SVD, singular value decomposition method and damped least-squares algorithm to solve geophysical inverse problem, the procedure is relatively simple to understand)

读取raw文件，函数文件输出具体矩阵数值(Read raw files, functions, file output specific matrix values)

平面应力、平面应变有限元数值计算,适合于有限元编程入门(plane stress and plane strain for numerical calcualtion)

说明：  无约束优化中的共轭梯度算法程序，解压缩后就可以用了(Unconstrained optimization of the conjugate gradient algorithm procedure can be extracted after the)
