matrix input if mat(1) is > than mat(2)

im trying to find if an mat(1)is > mat(2) and so on.

below is my attempt:

function [specialmax] = specialmax(x) 
[r c]=size(x) 
t=x(1,:);
for i=2:r 
  for j=1:c 
    specialmax=x(1,j);

function [specialmax] = specialmax(x) 
  [r c]=size(x) 
  t=x(1,:);
  for i=2:r 
    for j=1:c 
      specialmax=x(1,j); 
      ...

Need to set the initial condition outside the loop; you're overwriting specialmax each time with the first row value as it is.

function [specialmax] = specialmax(x) 
  [r c]=size(x);
  specialmax=(1,:);       % initialize to first row
  for i=2:r 
    for j=1:c 
      ...now updated if needs be, but do it in the output array...

Good try...just a tiny logic boo-boo :)
