最小二乘问题的研究现状

The Current Research of the Least-Square Problems

实际中,经常遇到最小二乘的求解问题.对于最小二乘问题的最优解法,专家学者们都在积极地研究、论证.为了能对最小二乘问题有初步的了解,本文就最小二乘问题的基本解法和近几年的成果进行简单的阐述.

Actually,we often meet the problem that how to solve the least-square problems.For the optimal solution of the least-square problem,specialists and scholars all actively research and demonstrate.In order to understand the problems preliminarily,this paper simply describes the basic solutions of the least-square problems and achievements in recent years.
