I am doing imagesegmentation on kidney using graphcut to segment kidneys which are grayscale images . i tried to use this below by Mohamed Athiq https://in.mathworks.com/matlabcentral/fileexchange/41526-gray-scale-image-segmentation-using-normalized-graphcuts but iam getting error
  1. In eigs/AminusSigmaBsolve (line 1213)
  2. In eigs>@(v)AminusSigmaBsolve(Bmtimes(v)) (line 149)
  3. In eigs (line 267)
  4. In graphcuts (line 91)
  5. Subscripted assignment dimension mismatch.
  6. Error in graphcuts (line 102)
  7. id(:,:)=se;
