Member Function Documentation

double QUESO::Generic1D1DFunction::deriv ( double  domainValue ) const

virtual

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

This function checks if point domainValue belongs to the domain of this function, and in affirmative case, it returns the value of the derivative at such point.

Implements QUESO::Base1D1DFunction.

double QUESO::Generic1D1DFunction::value ( double  domainValue ) const

virtual

Returns the value of the (one-dimensional) 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.
