◆ differentiate()

ExpressionCOP numeric::expression_parser::AddExpression::differentiate ( std::string const & varname ) const

overridevirtual

Returns the expression for the partial derivative of this expression by the variable named varname. If the partial derivative is always zero with respect to varname, returns null.

Implements numeric::expression_parser::Expression.

References numeric::expression_parser::BinaryExpression::e1(), and numeric::expression_parser::BinaryExpression::e2().

◆ operator()()

numeric::Real numeric::expression_parser::AddExpression::operator() ( ) const

overridevirtual

Returns the sum of expression 1 and expression 2.

get expression pointers; evaluate left and right hand sides of the expression; return the sum.
