说明：  用混合同余法生成两组伪随机数，利用投针试验求圆周率。软件：matlab。(Two groups of pseudo-random numbers are generated by the method of mixed congruence, and the circularity is calculated by the test of inserting needle. Software: MATLAB.)

傅里叶变换FFT和逆傅里叶变换IFFT 欢迎大家喜欢(FFT and IFFT)

说明：  基于单位功率因数控制策略的单相有源滤波，去掉非线性负载部分即为单相全控整流。开关器件采用IGBT。(Based on the unity power factor control strategy of single-phase active power filter, remove the part of non-linear load is the single-phase full-controlled rectifier. Switching device IGBT.)

说明：  1跨35米的车桥耦合程序。Fortran编写(1, 35 meters span bridge coupling procedures. Fortran write)

使用奇异值分解来帮助求解最小二乘问题，特别是在方程系数矩阵不满秩的情况下。(SGELSD computes the minimum-norm solution to a real linear least * squares problem: * minimize 2-norm(| b- A*x |) * using the singular value decomposition (SVD) of A. A is an M-by-N * matrix which may be rank-deficient.)

一个abaqus梁单元的UEL，配套了理论和inp文件，可以完美运行(A abaqus UEL beam element, supporting the theory and inp file, you can run perfectly)
