说明：  扩展有限元的Fortran代码，用于扩展有限元的数值仿真计算。(Extended finite element of the Fortran code for the extended finite element numerical simulation.)

《数值分析方法库 》本书选材内容丰富，包括了当代科学计算过程中涉及的大量内容：求特殊函数值、随机数、排序、最优化、快速傅里叶变换、谱分析、小波变换、统计描述和数据建模、偏微分议程数值解、若乾编码算法和任意精度计算等。本书科学性和实用性统一，不仅对每种算法进行了数学分析和比较，而且根据作者经验对算法给出了评论和建议，并在此基础上提供了用C++语言编写的实用程序。(《Numerical Recipes in C: The Art of Scientific Computing》, The product of a unique collaboration among four leading scientists in academic research and industry, Numerical Recipes is a complete text and reference book on scientific computing. In a self-contained manner it proceeds from mathematical and theoretical considerations to actual practical computer routines. With over 100 new routines bringing the total to well over 300, plus upgraded versions of the original routines, the new edition remains the most practical, comprehensive handbook of scientific computing available today.)

PMV，的热舒适指标计算程序VB编码，可供参考(PMV, thermal comfort index calculation program VB code, for reference)

惩罚函数法C语言相关程序 它将有约束最优化问题转化为求解无约束最优化问题：其中M为足够大的正数， 起"惩罚"作用， 称之为罚因子，F(x, M )称为罚函数。(Penalty Function Method C language-related program it would have constrained optimization problem is transformed into solving unconstrained optimization problem: where M is a sufficiently large positive number, from the " punishment" effect, called the penalty factor, F (x, M) called the penalty function.)
