I know the algorithm how it works. For illustration process i want to visualise output of opening by reconstruction in each iteration. in matlab the function just gives the final result obtained after stability is reached.
looking at the fucntion itself with edit imreconstruct, it calls a mex function for processing and there is no way to get individual output from imreconstruct.

No. You'd have to write that code yourself.

I'd start by searching the internet for a full description or pseudocode for doing morphological reconstruction.

previous=h_k;
current=(imdilate(previous,se) & x);
output=zeros(a,b,3);

while ~isequal(previous,current)

output(:,:,2)=current;

imshow(x);
subplot(1,2,2);
imshow(output);
pause(0.2);
end
close all
imshow(current);
