inline

Compute zero order forward mode Taylor coefficients for result of op = DivvvOp.

The C++ source code corresponding to this operation is

     z = x / y

In the documentation below, this operations is for the case where x is a variable and y is a parameter.

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.
argarg[0] index corresponding to the left operand for this operator; i.e. the index corresponding to x.
arg[1] index corresponding to the right operand for this operator; i.e. the index corresponding to y.
parameterIf x is a parameter, parameter [ arg[0] ] is the value corresponding to x.
If y is a parameter, parameter [ arg[1] ] is the value corresponding to y.
cap_ordermaximum number of orders that will fit in the taylor array.
taylorInput: If x is a variable, taylor [ arg[0] * cap_order + 0 ] is the zero order Taylor coefficient corresponding to x.
Input: If y is a variable, taylor [ arg[1] * cap_order + 0 ] is the zero order Taylor coefficient corresponding to y.
Output: taylor [ i_z * cap_order + 0 ] is the zero order Taylor coefficient corresponding to z.
Checked Assertions
  • NumArg(op) == 2
  • NumRes(op) == 1
