can't understand this statement

while impliminting the code for bilateral filtering from link

http://in.mathworks.com/matlabcentral/fileexchange/12191-bilateral-filtering

i took the input for a small sized image.but the cartoon function gives the following error

??? Error using ==> cartoon at 43 Input image A must be a double precision matrix of size NxMx3 on the closed interval [0,1].

how should i change the code to accommodate this image whose dimensions are 24*18 pixels

Thanks in advance :]

T = im2double(YourMatrix) ;
T2 = repmat(T, 1, 1, 3);
cartoon(T2)

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);

ok thanks .it was a syntax error(jus missin the square brackets)

T2 = repmat(T, [1, 1, 3]);
