3168	Wrong type or wrong number of arguments	Rüdiger Franke	Rüdiger Franke	"The following three models of the PowerSystems library fail with the error reported here, using OpenModelica r24644:
`PowerSystems.Examples.Spot.AC3ph.Machines`
`PowerSystems.Examples.Spot.TransmissionAC3ph.DoublePIlineTG`
`PowerSystems.Examples.Spot.TransmissionAC3ph.DoubleRXlineTG`

The following model reproduces the problem:
{{{
#!mo
package WrongDiagonal
  function f
    input Real[:] a;
    output Real[size(a,1) - 1, size(a,1) - 1] T;
  protected
    parameter Integer n = size(a,1);
  algorithm
    T := diagonal(ones(n-1));
  end f;

  model M
    parameter Real[:,:] T = f({1,2,3});
  end M;
end WrongDiagonal;
}}}

Checking or attempting to simulate `WrongDiagonal.M` gives:
{{{
[1] 13:55:10 Translation Error
Error occurred while flattening model WrongDiagonal.M

[2] 13:55:10 Translation Error
[/home/user/work/WrongDiagonal.mo: 8:5-8:29]: Wrong type or wrong number of arguments to diagonal(ones(n - 1)). (in component ).
