From what I can tell, this should do it:
%load RGB image
im = im2double(imread('peppers.png'));
%extract each channel
R = im(:,:,1);
G = im(:,:,2);
B = im(:,:,3);
%convert to opponent space
O1 = (R-G)./sqrt(2);
O2 = (R+G-2*B)./sqrt(6);
O3 = (R+G+B)./sqrt(3);

All that is not built into MATLAB, but MATLAB includes the lower level functions for you to build that capability yourself , particularly in the Image Processing Toolbox and the Computer Vision System Toolbox.

There are lots of color spaces you could use. Here are formulas for some of them: http://www.easyrgb.com/index.php?X=MATH
