说明：  LDL分解。作为矩阵方程数值解法最基础的矩阵分解算法，LDL算法可以高效分解对称矩阵。(LDL decomposition. Numerical Solution of matrix equation as the most basic matrix factorization algorithm, LDL decomposition algorithm can be efficient symmetric matrix.)

This is a Stack Class with Funtions Push,Pop, check Stack is Full or Empty Application: Change a number from Decimal to Binary

C语言实现大数的加法减法以及乘法,水平限于仅仅大学生水平学习使用。(Use C language to achieve that addition, subtraction, and multiplication of a big intger.)

分数值分析的一些ppt课件，很有用，在学习C的时候，可以用到这些博大精深的思想(Fractional value analysis ppt courseware, useful when learning C, you can use these profound thought)

一维等离子体的plrc—fdtd算法程序(one-dimensional plasma plrc- fdtd Algorithm)

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

FFT DIF 分裂基的C语言代码，比较好的说明了整个流程(FFT DIF split the base of the C language code, better explains the entire process)

提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

这些代码可以用于产生一系列随机数，可以根据需要使用。(These codes can be used to generate a series of random numbers may be used as needed.)
