Image into grayscale without using toolbox

This is my current code:
function out = luminance(current_img )
R=current_img(:,:,1);
G=current_img(:,:,2);
B=current_img(:,:,3);
I=.299*R + 0.587*G+0.114*B;
out=I;
end
I'm trying to make my image grayscale but that's not what's happening, what am I doing wrong?

That should work. What's the problem? Perhaps you want to cast it back to uint8 or something.
out = uint8(.299*double(R) + 0.587*double(G)+0.114*double(B));
or else just leave it as floating point and use [] in imshow to display it:
imshow(out, []);
