In this case problem is not in dimension of square matrix or calculator than in elements of matrix. Matrix 3x3 that you have mentioned is singular and it doesn't have eigenvalues (actually it has one and it is equal 0), matrix 5x5 that you have mentioned isn't singular and it has eigenvalues.
Try for example [[1,1,0],[1,1,1],[0,1,0]] and it will return eigenvalues.

Cheers,
Frane.

Xcas (see above) and WolframAlpha seem to disagree with your claim:

eigenvalues{{0, 1, 0},{1, 0, 1},{0, 1,0}}

Ceci n'est pas une signature.
