ProductQuadraticExp

Description

This fit function computes the product of a linear and exponential function. See ExpDecay and QuadraticBackground for details on the component functions.

(\mbox{A0}+\mbox{A1}\times x+\mbox{A2}\times x^2) \times  \mbox{Height}\times \exp(-\frac{x}{\mbox{Lifetime}})

This function may be used with the Fit v1 algorithm. However, it was originally added to Mantid as a named function for the purposes of detector efficiency calibration. Also see ProductLinearExp.
