WebA symmetric triangular matrix is necessarily diagonal. There is also a neat theory behind tridiagonal matrices, which can help: It is easy to show that for any real A there is an orthogonal matrix Q such that Q T A Q = H, where H is upper Hessenberg. If A is symmetric it then follows that H is symmetric as well and hence tridiagonal. WebA square matrix AN is antihermitian if it satisfies A^(H)=-A, (1) where A^(H) is of adjoint. For example, this matrix [i 1+i 2i; -1+i 5i 3; 2i -3 0] (2) is an antihermitian matrix. Antihermitian matrices will often called "skew Hermitian matrices" via mathematicians. ONE matrix molarity can be tested to see if it is antihermitian in the Wolfram Language use …
