  VecMapFunction (XPRSProblem *prob, std::string name, VecMapFunctor functor, int nIn)
 
virtual auto  call (int, std::vector< xpress::objects::Expression > arguments) -> xpress::objects::Expression override
  Create an expression that represents a symbolic call to this function.
Parameters
output If this is a multi-output function then this specifies which output to select. Note that the first output has index 1!
arguments Arguments for the function call.
Returns
The expression representing a call to this function.

auto  call (xpress::SizedArray< double const > const &values) -> double
 
virtual auto  evaluate (int, xpress::SizedArray< double const > const &args) -> double override
  Evaluate this function for the given values.Examples using evaluate:

Parameters
output Output selector. In case the function returns multiple outputs then this selects which of them to return. Otherwise this argument is ignored. Note that the first output has index 1!
args Arguments for the function call.
Returns
The result.
Since

Examples using evaluate:
 
virtual auto  isMultiOutput () -> bool override
  Check whether this is a function that produces more than one value for a single call.
Returns
true if the function has more than one output, false otherwise.
