T = im2double(YourMatrix) ;

i tried this with the input image
img3 = double(imread('Perovskite+QDs+VK5+Diffusion+on+Glass+VHigh+S2N+ideal+of+SPT_page9.tiff'))/255; T = im2double(img3) ; T2 = repmat(T, 1, 1, 3); cartoon(T2)
but am getting the following error
??? Error using ==> repmat Too many input arguments.
Error in ==> runDemo at 21 T2 = repmat(T, 1, 1, 3);
