Dear colleagues,

I suspect there is a simple answer to this question -- but I cannot find it.

Suppose I have a list of matrices. I want to pull out an element (such as
row 1, col 2) from each matrix. Do I need a loop to do this? Or is there an
easy way to index this?

Let Z denote the list of matrices. All matrices have the same order. I
want something like
  Z[[.]][1,2] (which of course will not work, but you get the idea)

Thanks for any and all tips,
