一本介绍fortran语言的不错的书籍，希望你喜欢，版权归属原作者，仅供学习交流(A good book for learning Fortran language, if you read it carefully, you will get what you want.)

求给定矩阵的逆矩阵和行列式值。已经经过测试，与matlab做了对比，计算结果可靠(Seeking a given matrix inverse matrix and determinant value. Has been tested with Matlab contrast, reliable calculation results)

共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一(Conjugate gradient method (Conjugate Gradient) is between the steepest descent method and Newton' s method between a method that takes only a first derivative information, but to overcome the slow convergence of the steepest descent method shortcomings, but also avoid the need to store Newton and computing the inverse Hesse matrix and disadvantages, conjugate gradient method is not only to solve large linear equations of the most useful methods, large-scale nonlinear optimization solution is the most efficient algorithms)

说明：  最优化课程中的最速下降法matlab程序，利用了wolfe搜索和armijo线搜索(Matlab program of steepest descent method in optimization course, using Wolfe search and Armijo line search)

本程序可用于线性插值,Fortran源码用于插值计算。(Program for linear interpolation.)

说明：  金属断裂的数值计算提供理论依据及实际详例解读(The numerical calculation of metal fracture provides theoretical basis and interpretation of practical examples)

说明：  矩阵求逆，使用fortran语言编写，希望能对有需要的朋友有所帮助(Matrix inversion, written in FORTRAN language, hoping to help friends in need)

说明：  隐马尔可夫的经典文献，和通俗易懂的PPT，很好的经典资料，文献常被应用，甚至PPT都经常被模仿(Hidden Markov classic literature, and user-friendly PPT, classic good information, the literature is often applied, or even PPT are often imitate)

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)

说明：  你输入一个长方体的长和宽以及高，就可以输出他的面积(input height，width，length，output volume)
