Abs highest(extreme) value in a matrix with +ve & -ve elements

[adla.raghu]

Hi guys,

A have a 2150*2150 matrix and I want to find the extreme value in each in
column/row retaining their +ve or  -ve symbol as well. 

Eg:   Say if I have -0.9965743234 and +0.7645334441 in a column/row  

    when I do:
      max(Result(:,2));
      It only gives me the max +ve value. i.e +0.7645334441 

      I need a command that gives me -0.9965743234

Also can I get the index values for all these highest values at a go.
 
Thanks in advance
