权重函数 weighting function
维基百科中的解释如下,请问那位知道比较形象化,直观一点的解释?
A weight function is a mathematical device used when performing a sum,integral,or average in order to give some elements more of a "weight" than others.They occur frequently in statistics and analysis,and are closely related to the concept of a measure.Weight functions can be constructed in both discrete and continuous settings.

权重函数就好像大家投票表决,公平的时候是一票顶一票,谁投的票都一样.可是有时候,不是一票顶一票,比如老板想让他投的票分量比别人重（比如一票顶2票）,就需要用上权重函数.权重函数给于老板那一票特别重的权重（分量）.计算学生成绩的“加权平均”也是这个道理.

请问MATLAB怎样调用function函数? 如：
matlab中function 函数怎么用?
“幂指函数”英语怎么说? power function 是 幂函数 exponential function 是 指数函
function() 什么意思 没有自定义函数 不是像这样 function abc()
权重是什么意思?
“权重”是什么意思?
用IF函数,完成率大于60%按照100%乘以权重,完成率40-60%之间按照60%乘以权重,40%以下为0,公式怎么写
如何在matlab中运行一下function函数
matlab中function定义函数,出现自变量未定义错误,是怎么回事?
