WebHermitian or real symmetric matrices are easy to understand: both classes are real vector spaces (a linear combination of Hermitian matrices with real coefficients is Hermitian, and same for real symmetric matrices). Unitary (or orthogonal) matrices are more difficult. Example: describe all 2 ×2 unitary matrices with determinant 1. Let our ... WebA determinant is a real number or a scalar value associated with every square matrix. Let A be the symmetric matrix, and the determinant is denoted as “det A” or A . Here, it refers to the determinant of the matrix A. After some linear transformations specified by the matrix, the determinant of the symmetric matrix is determined.
