$$\renewcommand\AA{\unicode{x212B}}$$

## Description¶

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

$\left(\mbox{A}_0 + \mbox{A}_1 x + \mbox{A}_2 x^2\right)\cdot h \cdot e^{-\frac{x}{\tau}}$

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.
