How to return a structure as a function output?

function [s, rx, ry] = ComputeR(frame);
[pyr,pind] = buildLpyr(frame,'auto'); %Building Laplace pyramid
nLevels = size(pind,1)-1; %no. of levels in the pyramid
kernelx = [0.0, 0.0, 0.0; 0.5, 0.0, -0.5; 0.0, 0.0, 0.0];
kernely = [0.0, 0.5, 0.0; 0.0, 0.0, 0.0; 0.0, -0.5, 0.0];

for k = 1:nLevels 
    
    s = pyrBand(pyr, pind, k);
    rx = conv2(s,kernelx);
    ry = conv2(s,kernely);
    
    S(k).s = s;
    S(k).rx = rx;
    S(k).ry = ry;  
end

end

Here this function is returning the values of s, rx, ry corresponding to the last 'k' value only. How can I get the whole values of S(k).s, S(k).rx and S(k).ry as my function output?

Hi, you need just one output, the structure itself. Its field are part of it... Or try to explain better what you mean by "How can I get the whole values of S(k).s, S(k).rx and S(k).ry as my function output?"

If you want the entire struct as the output, then you should make the struct the output:

function S = ComputeR(frame);
