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 exercise date and length.
The volatility matrix M must be defined so that:
- the number of rows equals the number of exercise dates;
- the number of columns equals the number of swap tenors;
M[i][j]contains the volatility corresponding to thei-th exercise andj-th tenor.
