Finding Maximum value in a loop

Hi all i am trying to find the maximum value in the loop below, can someone please help and explain

for i=1:100 for angle=-90:90;

phi=angle*pi/180;
xdata=[sin(sno+(phi))];
ydata=(m_mata(:,:,i))
R=(corrcoef(xdata,ydata));
      end

example Result from R are

 1.0000    0.6581
 0.6581    1.0000

within the loop above i want to find the maximum value of R(2,1) and also the associated angle that is been used in xdata to give the maximum of R(2,1).

basically I am wanting to find the maximum of R(2,1)and also the associated angle that is been used in xdata to give the maximum of R(2,1),for each time I run for i=1:100, for each loop I want to store the value of R(2,1) and the compare the new value with previous value if the new value is greater for when i=2 then this will be the maximum of R(2,1).If the maximum value of R(2,1) when i=2 is smaller then we use the maximum of R(2,1) when i=1 At the end of the iteration I want to end up with a maximum value of R(2,1) and also the associated phi

I am a bit inexperienced with programming and not sure how to capture this concept and put it in Matlab.

Your help is much appreciated.
