Class Documentation¶

template<typename ReturnT> class GaussianFunction1 : public lsst::afw::math::Function1<ReturnT>

1-dimensional Gaussian

f(x) = A e^(-x^2 / 2 sigma^2) where:

A = 1 / (sqrt(2 pi) xSigma) coefficient c0 = sigma

Public Functions

GaussianFunction1(double sigma)¶

Parameters

sigma: sigma

Construct a Gaussian function with specified sigma

GaussianFunction1(GaussianFunction1 const&)¶

GaussianFunction1(GaussianFunction1&&)¶

GaussianFunction1 &operator=(GaussianFunction1 const&)¶

GaussianFunction1 &operator=(GaussianFunction1&&)¶

~GaussianFunction1()¶

std::shared_ptr<Function1<ReturnT>> clone() const¶

Return a pointer to a deep copy of this function

This function exists instead of a copy constructor so one can obtain a copy of an actual function instead of a useless copy of the base class.

Every concrete subclass must override this method.

Return: a pointer to a deep copy of the function

ReturnT operator()(double x) const¶

std::string toString(std::string const&) const¶

Return a string representation of the function

Return: a string representation of the function
