classGaussianFunction1: 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
