Information

Contains a C sub routine of robust pole assignment to modify the eigenvector matrix X according to Kautsky algorithm

Interface

function modifyX_old
  import Re = Modelica.ComplexMath.real;
  import Im = Modelica.ComplexMath.imag;
  input Complex X[:, size(X, 1)] "Complex eigenvector matrix";
  input Complex S[size(X, 1), :] "Complex eigenvector matrix";
  input Integer m "Rank of the system input matrix B; S_real and S_imag must have n*m columns";
  input Integer ncp "number of complex pairs";
  input Integer steps "Number of iterations";
  output Complex Xm[size(X, 1), size(X, 2)];
end modifyX_old;
