The symbolic eigenvalues of a square matrix A or the symbolic eigenvalues and eigenvectors of A are computed, respectively, using the commands

Code:

E = eig(A)
[V,E] = eig(A)

The variable-precision counterparts are

Code:

E = eig(vpa(A))
[V,E] = eig(vpa(A))

The eigenvalues of A are the zeros of the characteristic polynomial of A, ie. det(A-x*I).
