此源码包是我本学期最优化理论课程的大作业，其中包括了我自己写的以下常用最优化算法的实现代码：最速下降法，牛顿法，非线性最小二乘法，DFP法。fun1，fun2是两个测试函数。谢谢！(This is my source packages optimization theory this semester courses in large operations, including my own to write the following commonly used optimization algorithm code: steepest descent method, Newton method, nonlinear least squares method, DFP method. fun1, fun2 are two test function. Thanks!)

欧拉向后差分格式的程序文件，可直接调用，在科学计算中有很重要的应用.(Euler backward difference scheme of program files can be called directly,which have important applications in scientific computing.)

主要用来进行Umat子程序指导编程说明用的文件(The document is mainly used for writting a Umat project by fortran language.)

说明：  线性判别分析（LDA，全称Fisher Linear Discriminant Analysis）算法的C#实现源码，根据stprtool box for matlab中的LDA.m编写。用到MathNet库做相关的矩阵运算，使用zedgraph控制绘图。有简单的测试数据。( C# source code of linear discriminant analysis (LDA, full name of the Fisher Linear Discriminant Analysis) algorithm , according to LDA.m of stprtool box for matlab . Use MathNet library to do matrix operations,and use zedgraph control for drawing. Thers has a simple test data.)

牛顿迭代法，用于求解非线性方程，具体使用方法见程序内部说明。(Newton iteration for solving nonlinear equations, the specific use of the procedure see the internal note.)

svg电力控制系统的仿真论文，很详细。包括系统的软件硬件，大部分为原创！包括matlab-fuzzy pi算法的实现(svg power control system simulation study, very detailed. Including system software and hardware, most original!)

《最优化理论与方法》书籍中的乘子法的源程序，该书中的很多案例都用此方法试验过，本代码是一个小案例，将目标函数和约束函数按自己的需求换掉就能进行所期望的运算(" Optimization Theory and Methods" books multiplier method of the source, the book' s many cases are tested using this method, the code is a small case, the objective function and constraints to replace it according to their needs can perform the desired operation)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)
