Problem padding a 3d array

Hi I have a nested structure of 25 structures of 1x1 stuct, the 1x1 struct contains an array of Nx3 double values that I wish to store in an array of Nx3x25. So there are 25 segments of varying length (194-200). The code below fills the array contours with the minimum 194x4x25. I set d to the max N=200.

contours=zeros(d,3,25);

for i = 1:25    
    contours(:,:,k)=c(k).segments.points;
end

I have tried various ways of padding but can't seem to get any to work. I hope this is enough information. Any ideas please? James

I cracked it eventually, it did not help that I had a k instead of the i as the index.

for i = 1:25    
    s=size(c(i).segments.points,1);
    contours(:,:,i)=padarray(c(i).segments.points, [(d-s),0],0,'post');
end
