INonLDVariables.FindById

Syntax

FindById(Id:String): INonLDVariable;

Parameters

Id - identifier of searched variable.

Description

The FindById method searches for the variable in the collection by its identifier.

Example

Executing the example requires the Optima variable that contains a system of non-linear equations and parameters for its calculation. The system of equations must include a variable with the "x1" identifier.

Sub Main;

Var

Optima: NonLinearDecomposition;

PeriodL, j, i: Integer;

Vars: INonLDVariables;

Vrbl: INonLDVariable;

Res: INonLoResults;

val: Double;

Begin

// Calculate system

PeriodL := 4;

Res := Optima.Evaluate(PeriodL) As INonLoResults;

Debug.WriteLine(Res.ErrorMsg);

// Display results

If (Res.Status = 0) Then

Vars := Optima.Variables;

Vrbl := Vars.FindById("x1");

Debug.WriteLine("Variable: x1");

For i := 0 To PeriodL - 1 Do

Val := Res.VarValues(Vrbl.Id)[i];

Debug.WriteLine(Val);

End For;

End If;

End Sub Main;

After executing the example a system of non-linear equations is created and calculated. Data of the x1 variable is displayed in the console window.
