TMtxOptimization.RealFunction Property

property RealFunction: TRealFunction;

Defines the function to be minimized.

Returns: TRealFunction

Remarks:

Defines the function to be minimized. The TMtxOptimization.RealFunction must be of the TRealFunction type. Before you write actual function, set the Parameters, Constants and PConstants array size by using the:

TMtxOptimization.VariableParameters vector Length, Size or SetIt method,
TMtxOptimization.ConstantParameters vector Length, Size or SetIt method,
TMtxOptimization.SetObjects method

Examples

MtxOptimization->VariableParameters->SetIt(false,OPENARRAY(double,(1,1)));
MtxOptimization->ConstantParameters->SetIt(false,OPENARRAY(double,(2.5)));

double __fastcall BTestFunction(TVec* const Parameters, TVec* const Constants, System::TObject* const * ObjConst, const int ObjConst_Size)
{
    double* Pars = Parameters->PValues1D(0);

    return 2*Pars[0] + Sqrt(Pars[1]-Consts[0]);
}

MtxOptimization->RealFunction = TestFunction;

function TestFunction(const Pars: TVec; const Consts: TVec;const ObjConsts: Array of TObject): double;
begin
    TestFunction := 2*Pars[0]+Sqrt(Pars[1]-Consts[0]);
end;
