Some mathematical topics circulant matrices, are pure gems that cry out to be admired and studied with different techniques orperspectives in mind.
I will show in this paper many points about circulant matrix. And answer many questions such as, Is circulant a subspace of the set of the vector space of (n × n) matrices? I shell Discuss properties the circulant matrix. Is commutative or no, is a nonsingular or not, Is symmetric or not. Will the transpose and inverse (if it exists) of A also be circulant. I will discuss the eigenvalues and eigenvectors of A. Finally, discussion one application of circulant matrix.
