Hello Everybody,

I tried to use the Cholesky decomposition and got an unexpected error.
The simplest example of the model is:

model test
  Real msr_mat[2, 2];
equation
  msr_mat = Modelica.Math.Matrices.cholesky({{1,0},{0,1}}, false);
end test;

The corresponding error message is:

"[/usr/lib/omlibrary/Modelica 3.2.1/Math/package.mo:2463:7-2466:15:readonly]
Error: Type mismatch in assignment in H := {} of Real[size(A, 1), size(A, 2)] := Integer[0, 0]
Error: Error occurred while flattening model test"

Please help to explain this behavior.

Thanks in anticipation.
