摘要
文章介绍了拉格朗日插值和最小二乘曲线拟合两种方法,进行对比分析,对数据进行曲线插值拟合,并进行预测精度对比,最后通过实例解算论述了两种方法在建筑物荷载变形监测中都有一定的应用价值。
This paper introduces the Lagrange interpolation and least squares curve fitting two methods, comparative analysis, curve fitting to the data, and the prediction accuracy of comparison, finally through an example calculation discussed two methods of deformation monitoring has certain application value in the load of the building.
