Re: [Quantlib-users] Calibration short rate models

[Luigi B. <lui...@gm...>]

Hi,
    the example uses a flat curve just for simplicity; by doing so, it
focuses on the calibration code without adding too much code to set up a
term structure.  In a real case, you'd use the full term structure.

Hope this helps,
    Luigi
