This is a specialization of IFunction for functions of one real argument.
Represents the Jacobian in IFitFunction::functionDeriv.
Implements the part of IFunction interface dealing with parameters.
Provide Streteched Exponential fitting function: h*exp(-(x/t)^b )
void function1D(double *out, const double *xValues, const size_t nData) const override
Function you want to fit to.

overwrite IFunction base class methods
const std::string category() const override
The categories the Fit function belong to.
void functionDeriv1D(API::Jacobian *out, const double *xValues, const size_t nData) override
Derivatives of function with respect to active parameters.
Helper class which provides the Collimation Length for SANS instruments.
