This class calculates time-dependent Black volatilities using
as input a vector of (ATM) Black volatilities observed in the
market.
The calculation is performed interpolating on the variance curve.
Linear interpolation is used as default; this can be changed
by the setInterpolation() method.
Black volatility curve modelled as variance curve
This class calculates time-dependent Black volatilities using as input a vector of (ATM) Black volatilities observed in the market.
The calculation is performed interpolating on the variance curve. Linear interpolation is used as default; this can be changed by the setInterpolation() method.
For strike dependence, see BlackVarianceSurface.
