地球物理反问题中带约束的Tikhonov正则化方法的应用(applications of constrained regularization method )

管型燃烧固体火箭发动机压强建立过程计算程序 输入为比热比，燃气气体常数，点火温度，推进剂密度，装药直径（内径和外径），喷管喉部直径，装药体积，燃速相关常数 输出为压强和工作时间(tube type of solid rocket motor combustion pressure build process calculation programs for heat input than, gas gas constant, the ignition temperature, propellant density, charging diameter (inside and outside), nozzle throat diameter, charging volume, burning rate pressure and related constant output to work time )

等几何分析MATLAB程序包,有着丰富的例子,其中fem包内为传统的拉格朗日插值有限元, iga包内为nurbs插值的等几何有限元(This is the README file for the Isogeometric Analysis (IGA) Matlab code. The code supports one, two and three dimensional linear elasticity problems. Extended IGA for hole, inclusion and crack modelling is also implemented.)

ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)
