See my Answer/demo in your duplicate posting: http://www.mathworks.com/matlabcentral/answers/16042-convert-grayscale-image-to-color-image
There I split out the RGB channels. It's the same principle to get Y, Cb, and Cr
Y = ycbcrImage(:,:, 1);
Cb = ycbcrImage(:,:, 2);
Cr = ycbcrImage(:,:, 3);

Ran in:
As of R2018b, you can also use imsplit()
% read an image (RGB,uint8)
rgbpict = imread('peppers.png');
% convert to uint8-scale YCbCr
yccpict = rgb2ycbcr(rgbpict);
% split the image into its components
[Y Cb Cr] = imsplit(yccpict);
% display them side by side
imshow([Y Cb Cr],'border','tight')
