void CppAD::local::forward_exp_op_0 ( size_t  i_z,
size_t  i_x,
size_t  cap_order,
Base *  taylor 
)
inline

Zero order forward mode Taylor coefficient for result of op = ExpOp.

The C++ source code corresponding to this operation is

     z = exp(x)
Template Parameters
Basebase type for the operator; i.e., this operation was recorded using AD< Base > and computations by this routine are done using type Base .
Parameters
i_zvariable index corresponding to the result for this operation; i.e. the row index in taylor corresponding to z.
i_xvariable index corresponding to the argument for this operator; i.e. the row index in taylor corresponding to x.
cap_ordermaximum number of orders that will fit in the taylor array.
taylorInput: taylor [ i_x * cap_order + 0 ] is the zero order Taylor coefficient corresponding to x.
Output: taylor [ i_z * cap_order + 0 ] is the zero order Taylor coefficient corresponding to z.
Checked Assertions
  • NumArg(op) == 1
  • NumRes(op) == 1
  • i_x < i_z
  • 0 < cap_order
