What is this tuple assignment error?

function SVDRLS
  annotation(Diagram(coordinateSystem(extent={{-148.5,-105.0},{148.5,105.0}}, preserveAspectRatio=true, initialScale=0.1, grid={5,5})));
import Modelica.Math.Matrices;
  input Real A[3,2];
  output Real sigmasvd[3,2];
  output Real Usvd[3,3];
  output Real VTsvd[2,2];

algorithm
(sigmasvd,Usvd,VTsvd):=Matrices.singularValues(A);

end SVDRLS;

[<interactive>:10:1-10:50:writable] Error: Type mismatch in assignment in (sigmasvd,Usvd,VTsvd) := Modelica.Math.Matrices.singularValues({{A[1,1],A[1,2]},{A[2,1],A[2,2]},{A[3,1],A[3,2]}}) of (Real[3, 2], Real[3, 3], Real[2, 2]) := (Real[:], Real[:, :], Real[:, :])
[<interactive>:10:1-10:50:writable] Error: Tuple assignment only allowed when rhs is function call (in Modelica.Math.Matrices.singularValues({{A[1,1],A[1,2]},{A[2,1],A[2,2]},{A[3,1],A[3,2]}}))

i will ask wolfram guys but can you tell me what to ask in terms of compiler/building terms...how to ask the correct technical question

thanks

Thank you very much but problem persists

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);

Hi!
I am a new user of modelica. I am trying to run a hybrid simulation of recursive least square (discrete) and a sine wave (continuous). In a nutshell, i sample the sine wave and try to do the least square estimation of the curve of sine wave (meaning fitting the curve with a line). just like moving average filter, i perform estimation using three sample values; forgetting(ignoring) previous ones and recieving the new ones.

so when i run the code i get the following error.

a->dim_size[0] != b->dim_size[0], 1 != 2
Assertion failed: base_array_shape_eq(source, dest), file real_array.c, line 177

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

my code is
