I want to find out SVD of a 7X7 matrix(small block of an frame) for frames in temporal direction.

I want to find out SVD of a block, of a frame in temporal direction but I am getting error"Undefined function 'svd' for input arguments of type 'uint32'"

for num=1:NumberOfimages
    km{:,:,num}= rgb2gray(uint32(imread(sprintf('path of frames',num))));
    im=km{:,:,num}; 
for i=24
        for j=24
            submatrix = im(24:30, 24:30);
            S=svd(submatrix);
            SCELL{:,:,num}=S;%stores all the eigen values 

         end
     end

   end

Use:

S = svd(double(submatrix))
