Remove function dorgqr_x

[tobolar]

Function M_LS2.Math.Matrices.LAPACK.dorgqr_x shall be replaced with Modelica.Math.Matrices.LAPACK.dormqr. But modelica/ModelicaStandardLibrary#4388 shall be resolved first since otherwise the new function call would look like:
Modelica.Math.Matrices.LAPACK.dormqr(Q, Q, tau, "L", "N"), i.e. with doubled input of Q, which is odd.

It seems the following replacement could be possible (to correct my message above):

(Aout, info) := Modelica.Math.Matrices.LAPACK.dormqr(identity(size(Q, 1)), Q, tau, "L", "N");

instead of

(Aout, info) := Modelica_LinearSystems2.Math.Matrices.LAPACK.dorgqr_x(Q, tau);

with a predecessor (in both cases)

(Q, tau, info, work) := Modelica.Math.Matrices.LAPACK.dgeqrf(A);

@tobolar, I think this issue can be closed, see your comment in modelica/ModelicaStandardLibrary#4388

You are right, the issue is closed.
I changed the milestone now since I still tend to remove dorgqr_x from LinearSystems2 because it is not used elsewhere.
