## How many eigenvalues does a 3×3 matrix have?

So a square matrix A of order n will not have more than n eigenvalues. So the eigenvalues of D are a, b, c, and d, i.e. the entries on the diagonal. This result is valid for any diagonal matrix of any size. So depending on the values you have on the diagonal, you may have one eigenvalue, two eigenvalues, or more.

## Can eigenvalues be negative?

1) When the matrix is negative definite, all of the eigenvalues are negative. 2) When the matrix is non-zero and negative semi-definite then it will have at least one negative eigenvalue. 3) When the matrix is real, has an odd dimension, and its determinant is negative, it will have at least one negative eigenvalue.

## Do all matrices have eigenvalues?

Over an algebraically closed field, every matrix has an eigenvalue. For instance, every complex matrix has an eigenvalue. Every real matrix has an eigenvalue, but it may be complex. In particular, the existence of eigenvalues for complex matrices is equivalent to the fundamental theorem of algebra.

## Can eigenvalues be zero?

Geometrically, zero eigenvalue means no information in an axis. As we know the determinant of a matrix is equal to the products of all eigenvalues. So, if one or more eigenvalues are zero then the determinant is zero and that is a singular matrix. If all eigenvalues are zero then that is a Nilpotent Matrix.
