伪随机序列（N=4的M序列）的C语言编程实现，可以应用于相关分析法和最小二乘辨识的输入信号。(Pseudo-random sequence (N = 4 M-sequence) of the C programming language, can be used in correlation analysis and least squares identification of the input signal.)

说明：  PRP共轭梯度法优化计算，采用FORTRAN语言(PRP conjugate gradient method optimization, the use of FORTRAN language)

根据分好的单元，进行有限元分析。计算每个单元中四个高斯点的应力，应变，主应力以及位移。(According to sub-good unit, finite element analysis. Calculated for each unit in the four Gauss point stress, strain, principal stresses and displacements.)

重力勘探多次滑动平均方法。给出地址参数，建立网格模型，按网格进行滑动平均。得到平滑后的重力数据。可以去噪。(gravity window moving iteration)

计算半方差，如果按克里金法计算插值要求计算半方差，用此程序可实现。(Calculation of semi-variance, if the Kriging interpolation method call for the calculation of semi-variance, using this procedure can be realized.)

数值分析，即计算方法课程中的龙贝格算法源代码。(Numerical analysis, calculation of the Romberg algorithm source code in the methods courses.)
