Inheritance diagram for SwaptionVolatilityMatrix:

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 thei-th option andj-th tenor.

Member Function Documentation
| void update | ( | ) | [virtual] |
This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.
Reimplemented from LazyObject.
| void performCalculations | ( | ) | const [virtual] |
This method must implement any calculations which must be (re)done in order to calculate the desired results.
Implements LazyObject.
