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);

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')
