Sparse Impl Prices

Key Sparse Impl Prices? in Vol Curve refers to an optional Boolean that determines whether the table with the theoretical (i.e. implied by the calibrated SABR model) swaption prices associated with the key _Sparse Impl Prices is generated as soon as the contents of a Vol Curve object are displayed.
Note this Boolean affects only the display of the object's contents, since for efficiency reasons the mentioned table will never be generated during the creation (but not display) of a Vol Curve object.
TRUE leads to the table generation.
FALSE obstructs the table generation.
If omitted, default is FALSE for enhanced efficiency during the display of the object's contents.
