Synopsis

integer*8 function evaluator_derivative (evaluator, name) integer*8 ::
evaluator character(len=*) ::  name end function evaluator_derivative

Description

Create evaluator for derivative of function represented by given evaluator object. Evaluator object is identified by evaluator handle and derivation variable is determined by name argument. Calculated derivative is in mathematical sense correct no matters of fact that derivation variable appears or not in function represented by evaluator.

Return value

64-bit integer uniquely identifying evaluator object representing derivative of given function.
