一个自己写的，生成BA无标度网络并计算其度分布的程序，fortran77格式，并附图一张，数据一份。(A program written myself, which can generate the BA scale-free networks and calculate the degree distribution , fortran77 format attachment is a drawing and data.)

feap 有限元程序，国外某大学的开源程序(feap finite element program)

这是一个求解NACA0012翼型在不同马赫数与攻角下的流场的Fortran源代码。计算格式采用了原始AUSM、AUSMDV以及AUSM+格式。为了提高计算精度，使用了不同限制器的MUSCL插值。(This is a Fortran source code for solving the flow field around the NACA0012 airfoil at different Mach numbers and angles of attack. The scheme of AUSM, AUSMDV and AUSM+ are employed for this code. In order to improve the calculation accuracy, the MUSCL interpolation with various type limiter are used.)

奇异值能量差分谱计算，可用于信号降噪处理(Singular value of the energy difference spectrum calculation can be used for signal noise reduction)

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.)

该程序是一种最小二乘滤波算法的matlab实现程序，主要应用于非平稳信号的干扰抑制中(The program is a least squares filtering algorithm matlab implementation program, mainly used in non-stationary signal interference suppression in)

数值代数通常也称为矩阵计算，是以计算机为工具来求解各种数学模型的主要课程，同时也是计算方法课程的延续和深入(Numerical algebra also commonly called matrix calculation is based on the computer as a tool to solve a variety of mathematical models of the main course, but also the calculation method of curriculum continuity and depth)

说明：  分数傅里叶变换和分数余弦变换，动态展示实部，虚部和模值(Computation of the Fractional Fourier Transform)

对FFT算法的基2时析型实现，在实习时很多专业会用到(Algorithm based on FFT analysis of type 2 o)

说明：  本书详细介绍了格子波尔兹曼法的原理，边界条件，具体模型及数值方法，非常适合学习与应用。(This book introduce the theory of lattice boltzmann methods alone with it's boundary conditions,models and numerical methods. It's really a book for us to learn and use.)
