 For a square matrix, the trace of a matrix is the sum of the elements on the main diagonal,
 which is equal to the sum of all its eigenvalues with multiplicities. Similarly, the determinant
 of a square matrix is the product of all its eigenvalues with multiplicities.
-If the determinant is not zero, the matrix is invertible and the linear equation system it
