摘要
在实际工程试验与研究中 ,多元数据处理经常遇到 ,根据 Weierstrass定理 ,采用多项式拟合是一种常见的数据处理方法。对于多元多项式的系数求解问题 ,可以归结为超定方程组的求解问题。该文以超定方程组的 SVD求解算法为核心 ,阐述了在工程实际中关于多元数据处理的一种应用方法 。
Multi-variable data process is usually used for the test and research of the practical project. According to the Weierstrass Theorem, polynomial fitting is a common way to process data. Resolving the coefficients of polynomial is equal to resolve corresponding linear algebra equations. Centering on the SVD resolving algorithm for the linear algebra equations, this paper discusses an applicable method about multi-variable data processing in the practical project, and tries to resolve the Multi-variable polynomial fitting with a simplified method
