Use rgb2gray:
hsvImage = rgb2hsv(rgbImage);
% Now do some computations on the HSV image.
% Now convert back to RGB
rgbImage2 = hsv2rgb(hsvImage);
% Convert to gray scale
grayImage = rgb2gray(rgbImage2);

a=imread(img);
b=rgb2hsv(a);
c=a(:,:,3);

That totally ignores the hsv image, and just sets c equal to the blue channel of the original RGB image.
