最小二乘法的例程,可以对数据进行线性拟合.由于源码较短只能进行直线拟合,曲线拟合的源码我稍后上传.-least squares method of programming, with the linear data fitting. As the only source for a shorter fitted to a straight line Curve fitting, I later upload source.

有限元线法三维问题的应用 主要求解平面单元，轴对称单元以及空间矩形直条单元-The application of the finite element-line method of three-dimensional problem solve plane unit, the axisymmetric unit as well as the space rectangular straight bar unit
