matrix diagonalization

In the diagonalization operation of a matrix A.

[Q Gamma] = eig(A)

Q=
  1.0000         0   -1.0000         0
         0    1.0000         0   -1.0000
         0         0    0.0000         0
         0         0         0    0.0000

Gamma=
  -0.0113         0         0         0
         0   -0.0253         0         0
         0         0   -0.0113         0
         0         0         0   -0.0253
"Warning: Matrix is close to singular or badly scaled.     Results may be
inaccurate. RCOND = 1.887379e-016."

It seems that the eigenvalues are not different and the diagolization is
actually failed.


However, I was expecting the matix diagonalizable for further mathematical
reasoning. I am wondering whether there is any techniques dealing with the
matrix that can NOT be diagonalizable?


Thank you very much for your attention.
