fft

根据试试数据 对变压器技术参数进行校核 利用的是最小二乘曲线拟合的方法(According to the data to try check technical parameters of the transformer is the least squares curve fitting using the method)

说明：  一维黎曼问题，一维问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度两步差分格式进行数值求解。(Riemann problem, One dimensional problem, the shock tube problem, is a typical one-dimensional compressible non viscous gas dynamic problem with analytic solutions. It is solved numerically by two order two step difference scheme.)

实现构建矩阵，矩阵的相加，相减，清零，以及转置，还有相乘的功能。(To build matrix, the matrix addition, subtraction, reset, and transposed, and the function of the multiplication. )

用于求解线性方程组的追赶法！！！程序经过优化处理，运行速度快，且注释完全易于阅读，欢迎大家下载！！(Solving linear equations for the law to catch up! ! ! Optimized procedures to deal with, fast, and completely easy-to-read notes, welcome you to download! !)

FLUENT里面改进的SA湍流模型，为UDF文件，可以进行链接编译计算(FLUENT which improved SA turbulence model for the UDF file can be compiled to calculate the link)

fluent中关于co2的真实气体模型的自定义程序(fluent in about co2 real gas model custom program)

系统仿真导论第一个实验程序，龙格库塔实验程序(Introduction The first experimental system simulation program, Runge-Kutta experimental procedures)

说明：  含随机出题（四则运算）及其迭代程序、返回数组中最大子数组和及其迭代程序等。(Software class operations, including four operations and iterative procedure, returns an array of sub-arrays and the largest and Iterative procedures)

FFT快速傅里叶变换，用于数字信号处理，大大提高了运行速度，节省内存开销。C语言实现(FFT fast Fourier transform for digital signal processing, greatly improving the speed and save memory overhead. C language)
