HI friends.I have a question:what is the difference between imshow & imagesc in this code and why the time reduce??

% matrix(10*i-9:10*i ,10*j-9:10*j)=rand;
% matrix(4*i-3:4*i ,4*j-3:4*j)=rand;
end
end
imshow(matrix);
imagesc(matrix);

% matrix=100*floor(5*matrix);
% matrix=83*matrix;
randmatrix{n}=matrix;
% matrix=randmat{n};
% imshow(matrix)
% matrix=floor(4*matrix);
% matrix=83*matrix;
% randmatrix{n}=matrix;
end

There two different functions, so I wouldn't expect them to take the same time.
Isn't your question answered simply by looking at the documentation?
I would recommend you reduce the clutter in question by removing all these useless comments.
