Note that row = y and is the first index, not the second index.
redValue = rgbImage(y, x, 1);
greenValue = rgbImage(y, x, 2);
blueValue = rgbImage(y, x, 3);

Since RGB images are really 3D matrices, you can use the squeeze command :
pixelRGB = squeeze(yourImage(x,y,:));

use function impixel if you have image processing toolbox
P = impixel(RGB,c,r)
