PowerLaw

Description

A power law may be used to describe:

\[y = ax^b + c\]

where: - a - magnitude - b - exponent - c - is a constant

Examples

An example of when this might be used is for spin relaxation modelling [1].

Properties (fitting parameters)

Name	Default	Description
Magnitude	1.0	coefficient for linear term
Exponent	1.0	exponent
Constant	0.0	coefficient for constant term
