在 MATLAB Online 中打开

RGB = rand(640, 480, 3);
R   = RGB(:, :, 1);
G   = RGB(:, :, 2);
B   = RGB(:, :, 3);
Rv = R(:);            % Vectors for each channel
Gv = G(:);
Bv = B(:);
RGBv = [Rv; Gv; Bv];  % All as 1 vecor
Out = reshape(RGBv, 640, 480, 3);  % Restore original immage:
isequal(RGB, Out)     % Success:    
ans = logical
