灰色关联度matlab源程序，灰色关联度分析法是将研究对象及影响因素的因子值视为一条线上的点,与待识别对象及影响因素的因子值所绘制的曲线进行比较,比较它们之间的贴近度,并分别量化,计算出研究对象与待识别对象各影响因素之间的贴近程度的关联度,通过比较各关联度的大小来判断待识别对象对研究对象的影响程度。(Gray correlation matlab source code, gray correlation analysis method is to study the factors and factors affecting the value of the points as a line, with the object to be identified and factors affecting the value of the factor curves drawn compares them to the between the proximity, and were quantified to calculate the object to be identified with the study of factors affecting the degree of correlation between the close degree of correlation by comparing the size of the object to be identified to determine the degree of influence on the study.)
