.Modelica_LinearSystems2.Math.Matrices.Internal.hohoTrafoUpperHess

Information

This function calculates one step in the calculation of upper Hessenberg form. Therein it calculates the r'th column of the Hessenberg matrix which is of shape {x,x,fill(1,n-r-1)}.

Interface

function hohoTrafoUpperHess
  extends Modelica.Icons.Function;
  import Modelica.Math.Vectors.length;
  input Real A[:, size(A, 1)];
  input Real u[size(A, 1)] "householder vector";
  input Integer r;
  output Real SAS[size(A, 1), size(A, 1)];
end hohoTrafoUpperHess;
