h = hessenberg(a)
[t, h] = hessenberg(a)
Converts a matrix to Hessenberg form and returns the unitary transformation matrix. The Hessenberg form of a matrix has elements equal to 0 below the first subdiagonal.
|a||Specifies a square matrix.|
|h||Returns a in Hessenberg form. h is a matrix of the same size as a. If a is a symmetric or Hermitian matrix, h is tridiagonal.|
|t||Returns the unitary transformation matrix. t is a matrix of the same size as a.|
The Hessenberg matrix h satisfies the following unitary similarity transformation: a = t*h*t' with t*t' = t'*t = eye(size(a)).
The following table lists the support characteristics of this function.
