derivative()

double lsst::gauss2d::fit::Log10Transform::derivative ( double x ) const

inlineoverridevirtual

Return the derivative of this tranform at the value x.

Implements lsst::modelfit::parameters::Transform< double >.

description()

std::string lsst::gauss2d::fit::Log10Transform::description ( ) const

inlineoverridevirtual

Return a description of this transform.

Implements lsst::modelfit::parameters::Transform< double >.

Definition at line 82 of file transforms.h.

{ return "Base 10 logarithmic transform"; }

forward()

double lsst::gauss2d::fit::Log10Transform::forward ( double x ) const

inlineoverridevirtual

Return the transformed value of x.

Implements lsst::modelfit::parameters::Transform< double >.

Definition at line 93 of file transforms.h.

{ return log10(x); }

repr()

std::string lsst::gauss2d::fit::Log10Transform::repr ( bool name_keywords = false, const std::string_view & namespace_separator = parameters::Object::CC_NAMESPACE_SEPARATOR ) const

inlineoverridevirtual

Return a full, callable string representation of this.

Parameters

name_keywords	Whether to prefix arguments with "{name}=", where name is the arg name in the header (as with keyword arguments in Python).
namespace_separator	The string to use to delimit namespaces, i.e. :: in C++ and . in Python.

Returns

A callable string representation of this, which should return an an identical object to this.

Note

The representation with name_keywords=false must be callable in C++. The representation with name_keywords=true should be callable in Python, if there are any bindings.

Implements lsst::modelfit::parameters::Object.
