greenchannel = rgbimage(:, :, 2);
The first page of an rgb image is the red channel, the 2nd is the green channel and the 3rd is the blue channel, hence the name rgb.

[r, c, p] = size(YourRGBArray);
GreenPlane = reshape(reshape(YourRGBArray,[], 3) * [0; 1; 0], r, c);
I do not recommend this for practical use; matrix indexing is faster and clearer.
