数据处理的等间距化GM(1,1)模型与方法

The Research of Equal Spaced GM(1,1) Model & Method to Data Processing

分析数据处理的现状后,运用灰色系统理论,建立了数据处理的等间距化GM(1,1)模型,给出了精度检验方法。编制了MATLAB程序,给出了数据处理实例。该模型不仅适合于等间距建模,也适合于非等间距建模,具有精度高、使用简便等特点,值得在数据处理中推广使用。

Based on grey system,an equal spaced GM(1,1) modeling and method to data processing in engineering field was put forward,the method of precision inspection was introduced.The programming was authorized with MATLAB6.1 language,and two examples were given.The model & method can be used for model establishing on equal interval,as well as on non-interval,which has high precision and easy to use. The model is simple and practical,and has a generalizing value in the field of data processing.
