Usage of Modelica.Math.Matrices?
Hi,
I have been trying to use the Matrices library within OMnotebook, so far without any success. Matrices.eigenValues with the following code:
class testeig
import Modelica.Math.Matrices;
Real A[3,3] = [1,2,3;3,4,5;2,1,4];
Real [3,3] eval;
Real [3,2] vals;
algorithm
(vals,eval):=Matrices.eigenValues(A);
end testeig;
When simulating I only got error messages. On Kubuntu
record SimulationResult
resultFile = "",
messages = "Simulation failed for model: testeig
[/usr/lib/omlibrary/msl31//Modelica/Math/package.mo:2089:7-2089:79:readonly] Error: Wrong type or wrong number of arguments to zeros(size(A, 1), size(A, 1))'.
(in component <NO COMPONENT>)
[/usr/lib/omlibrary/msl31//Modelica/Math/package.mo:1225:8-1225:81:readonly] Error: Class LAPACK.dgeev_eigenValues not found in scope Modelica.Math.Matrices.eigenValues (looking for a function or record).
Error: Error occured while flattening model testeig
",
timeFrontend = 0.0,
timeBackend = 0.0,
timeSimCode = 0.0,
timeTemplates = 0.0,
timeCompile = 0.0,
timeSimulation = 0.0,
timeTotal = 0.0
end SimulationResult;
and on Windows XP:
record SimulationResult
resultFile = "",
messages = "Simulation failed for model: testeig
end SimulationResult;
What changes do I have to make to get it working?
Calling the function in the equation block is also not working.
Thanks!

Thank you

Re: Usage of Modelica.Math.Matrices?
Hi,
I Have tried to use Modelica.Math.Matrices.solve(), but it doesn't seem to work (although the same code runs perfectly in Dymola). This is what I get:

I use OpenModelica 1.7.0.
Do you have any idea what I am doing wrong?

Re: Usage of Modelica.Math.Matrices?
You're doing nothing wrong. We had a name collision between our own dgesv_ and the one in Marices.LAPACK.
I now (hopefully) solved it in a new build:
