Re: ask for help on list operation


look at MapIndexed :

MapIndexed[(#1 - minlist[[Last@#2]] )/
((maxlist[[Last@#2]] - minlist[[Last@#2]])) &,
          A , {2}] // MatrixForm

or, elegantly using the list properties:

(# - minlist)/(maxlist - minlist) & /@ A  // MatrixForm
Map[ (# - minlist)/(maxlist - minlist) &, A]// MatrixForm

here the first "#" stands for the first row of A,
and you can subtract minlist from it (tough you cannot
subtract minlist from the whole A in one move, got to do
it row by row.
