Member Function Documentation

double QUESO::Constant1D1DFunction::deriv ( double  domainValue ) const

virtual

Returns the value of the derivative of the constant function at point domainValue.

This function checks if point domainValue belongs to the domain of this function, and in affirmative case, it returns 0 (derivative of a constant function.

Implements QUESO::Base1D1DFunction.

double QUESO::Constant1D1DFunction::value ( double  domainValue ) const

virtual

Returns the value of the constant function at point domainValue.

This function checks if point domainValue belongs to the domain of this function, and in affirmative case, it evaluates the function at such point, which is the constant value constantValue passed to the constructor of this class.

Implements QUESO::Base1D1DFunction.
