The eigenvals command finds eigenvalues of a matrix.
Remark: Xcas may not be able to find the exact roots of the characteristic polynomial in some cases. In that case, eigenvals(A) will return approximate eigenvalues of A if the coefficients are numeric or a subset of the eigenvalues if the coefficients are symbolic.
