BoundPenalty ( Vector x ) : double	Penalty function relative to bounds.
CalculateSingleRow ( object context ) : void	Calculates a single row of the objective function. Basically options with the same maturity and different strikes.
CalculateSingleRowWithInterpolation ( object context ) : void	Calculates call put prices for several strikes using controlled interpolation.
CalculateWeight ( double volume ) : double	Allows different specification of call/put weighting
FindExtremes ( Vector vector, Vector bounds ) : int[]	Finds the couple of integer {i,j} so that the values vector[i], vector[i+1],..., vector[j-1], vector[j] are all included in the interval (bound[0], bound[1]) while vector[i-1] and vector[j+1] are not.
HestonCallOptimizationProblem ( System.Matrix callMarketPrice, Vector maturity, Vector strike, Vector rate, Vector dividendYield, double s0, Vector matBound, Vector strikeBound ) : System
PutCallTest ( ) : void	Test method, displays a sensitivity on heston call and put prices.
SetVariables ( System.Matrix callMarketPrice, Vector maturity, Vector strike, Vector rate, Vector dividendYield, double s0 ) : void	Sets several variables used to solve the optimization problem.
