t5 = diff(lambda);
t5 = adjmat(t5);

At the top of your function put in
adjmat = @(M) mat2gray(M);

Is adjmat supposed to be computing the adjugate of the matrix t5. If so, you might be able to use this instead,

After diff function, the dimention of an array decreased by 1. I checked here Adjmat(t5) seems to align that. So you may try t5(:,1) = [] to replace t5 = adjmat(t5).
