Analysis of Deformation Prediction Based on Matlab's GM(1,1)Model

基于灰色GM(1,1)建模方法和模型检验方法,通过Matlab程序设计,实现了GM(1,1)程序化自动预测.通过实例说明了模型在工程建筑物变形量预测中的应用.分析表明,当系统呈指数变化时,预测值和后续实测值吻合度较好,可应用于二级精度标准的建筑物变形监测中.

The gray GM （1,1） modeling method and the model testing method are introduced in this paper. The automated forecasting model on GM （1,1） is realized by using MATLAB. It illustrates that this model is put into use in deformation of buildings. And researches show when the system changes exponentially, the field measurement coincides with the prediction. It can be applied to the secondary accuracy standard building deformation monitoring.
