Triggers TMtxOptimization recalculation. After the Recalculate call the Dirty property is set to false. 

The results are stored to:

• MinValue : RealFunction, evaluated at minimum.
• VariableParameters : minimum position.
• Iterations: Number of iterations needed to reach specified (Tolerance property) minimum precision.
• InverseHess : Inverse Hessian matrix (returned only by BFGS, ConjGrad and Marquardt methods).
• StopReason: Why did the optimization algorithm stop?
