摘　　要：等维新息模型是灰色模型的一种,它采用灰色理论中新陈代谢思想,即以增加一个新信息与去掉一个旧信息同时进行的方式建模,通过数据序列本身更新,纠正因时间变化而引起的偏差,比较客观地反映系统随时间变化的特性。在分析灰色预测模型基本原理的基础上,利用MATLAB强大的矩阵功能,在MATLAB平台上实现了等维新息灰色预测模型算法,并应用该算法给出了对国外装甲及反装甲武器发展的预测。The equal-dimensional information model was one of gray models. It adopted metabolism idea m gray theory and was established in such a way that added new information and gave up old information at the same time. The errors produced with time changing could be corrected by updating of the data sequence and the properties that system changing with time changing could be shown objectively. This paper presented the algorithm of the equal-dimension and new-info gray model and it had been implemented using the powerful probabilities of dealing with matrix on MATLAB platform. Using the theory presented in this paper, we have predicted the developments of armor and anti-armor weapons in the world.
