Detailed Description

Black volatility surface modelled as variance surface.

This class calculates time/strike dependent Black volatilities using as input a matrix of Black volatilities observed in the market.

The calculation is performed interpolating on the variance surface. Bilinear interpolation is used as default; this can be changed by the setInterpolation() method.
