Thanks for the answer. I hope a problem in due course it will be resolved.

Hello,
I am a new openmodelica user.
I try to write vector/matrix operations in algorithm section.
For example:

class mvmul

  Real res[3];

  Real m[3,3]={{1,0,0},{0,0.5,0},{0,0,1}};

  Real v[3]={1,1,1};

  algorithm

  res:=m*v;

end mvmul;

After "Check":

Class mvmul has 13 equation(s) and 15 variable(s). 12 of these are trivial equations.

After "Simulate" :

{"",""}

"Error: Too few equations, underdetermined system. The model has 1 equation(s) and 3 variable(s)

"

Result of 'm*v' has dimension [3] and res[3]. But system interpreted 'm*v' dimension as [1].
what is wrong in my code?

Thank you.
