Detailed Description

At-the-money swaption-volatility matrix.

This class provides the at-the-money volatility for a given swaption by interpolating a volatility matrix whose elements are the market volatilities of a set of swaption with given option date and swapLength.

The volatility matrix M must be defined so that:

*
the number of rows equals the number of option dates;
*
the number of columns equals the number of swap tenors;
*
M[i][j] contains the volatility corresponding to the i-th option and j-th tenor.

Member Function Documentation

void performCalculations () const [virtual]

This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.
