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

[adla.raghu]

Thanks for your reply, but  I am trying to retrieve only the extreme value in
each column retaining its -ve/+ve symbol.[and its index as well]

So when I do min(); it's giving me the minimum value in the column ignoring
the +ve values. 

Eg: if I have a column in A as [1,3,-5,7,-9,10]
         min(A(x)) returns -9 but the extreme value [abs max] is 10

     if I have another column in the matrix A as [1,3,-5,7,-9]
         max(A(x)) returns 7 while the extreme value is -9.

    So while looping through the entire matrix A, I either get the max
values or min but not the extreme values, the ones I am looking for. 

Thanks
