Properties of a Nilpotent Matrix
Following are some important properties of a nilpotent matrix:
- A nilpotent matrix is always a square matrix of order “n × n.”
- Nilpotency index of a nilpotent matrix of order “n × n” is always equal to either n or less than n.
- Both the trace and the determinant of a nilpotent matrix are always equal to zero.
- As the determinant of a nilpotent matrix is zero, it is not invertible.
- Null matrix is the only diagonalizable nilpotent matrix.
- A nilpotent matrix is a scalar matrix.
- Any triangular matrices with zeros on the principal diagonal are also nilpotent.
- Eigenvalues of a nilpotent matrix are always equal to zero.

Nilpotent Matrices are special types of square matrices, they are special because the product of a Nilpotent Matrix with itself is equal to a null matrix. Let’s take a square matrix A of order n × n it is considered a nilpotent matrix if Ak = 0. Here k is always less than equal to n.
In this article, we will learn about the Nilpotent Matrix in detail.
