乍一看,好像有两种不同的方式来确定相应时间需求: ·平均响应时间(Average response time ) ·绝对响应时间(Absolute response time);即, 所有的响应时间必须低于某一阀值 指定平均响应时间比较简单一些(straightforward),但是由于数据变化的干扰,这个需求往往难以实现。为什么取样中的20%的响应时间要比平均值高3倍以上呢...

A matrix is said to be lower matrix if all the elements above the diagonal of the given matrix are zero. So it is necessary that the elements must be zero.ExampleEnter the size of the matrix : 3 Enter an element : 0 Enter an element : 0 Enter an element : 0 Enter an element : ...
