Hi,

i am trying to use the QR decomposition from the LAPACK library. Its ok syntax wise but when i try to build/compile it the following error(s) pop up. please help

THE CODE:
Modelica.Blocks.Interfaces.RealInput errorsample ;
Modelica.Blocks.Interfaces.RealInput errorsample2 ;
Modelica.Blocks.Interfaces.RealOutput pcon ;
import Modelica.Math.Matrices;
Real A[3,2]; Real b[3];

Real Q [3,2]; Real QT [2,3]; Real R [2,2];

Real gammalyp[2](start=1.0, start=1.0);

Integer i(start=0);
Real pcon1,pcon2,pcon3,pcon4;
Real errsamp0,errsamp1,errsamp2,errsamp3;
parameter Real gamma=10;
parameter Real stime=0.1;

algorithm
when sample(0, stime) then
i:=i + 1;
if noEvent(i >= 4) then
A:=[pcon1,1;pcon2,1;pcon3,1];
b:={errsamp1,errsamp2,errsamp3};
(Q,R):=Matrices.QR(A);
QT:=transpose(Q);
gammalyp:=Matrices.solve(R, QT*b);

I created a more complete example, which works fine (at least compiles fine) in current omc. The Wolfram backend and code generation is different from the omc one though. You should try contacting them.

Code:

model M

  import Modelica.Math.Matrices; 

  Real A[3,2];   Real b[3]; 



  Real Q [3,2];   Real QT [2,3];   Real R [2,2]; 

  



  Real gammalyp[2](each start=1.0); 

  

  Integer i(start=0); 

  parameter Real stime = 0.2;

  Real pcon1 = 1;

  Real pcon2 = 1;

  Real pcon3 = 1;

  Real errsamp1 = 1;

  Real errsamp2 = 1;

  Real errsamp3 = 1;

algorithm 

  when sample(0, stime) then 

      i:=i + 1; 

    if noEvent(i >= 4) then 

      A:=[pcon1,1;pcon2,1;pcon3,1]; 

      b:={errsamp1,errsamp2,errsamp3}; 

      (Q,R):=Matrices.QR(A); 

      QT:=transpose(Q); 

     gammalyp:=Matrices.solve(R, QT*b);

   end if;

  end when;

end M;
