Prototype forward mode x op y (not used)

Template Parameters

Base	base type for the operator; i.e., this operation was recorded using AD< Base > and computations by this routine are done using type Base.

Parameters

p	lowest order of the Taylor coefficient that we are computing.
q	highest order of the Taylor coefficient that we are computing.
i_z	variable index corresponding to the result for this operation; i.e. the row index in taylor corresponding to z.
arg	arg[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.
parameter	If 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_order	maximum number of orders that will fit in the taylor array.
taylor	Input: If x is a variable, taylor [ arg[0] * cap_order + k ], for k = 0 , ... , q, is the k-th order Taylor coefficient corresponding to x. Input: If y is a variable, taylor [ arg[1] * cap_order + k ], for k = 0 , ... , q, is the k-th order Taylor coefficient corresponding to y. Input: taylor [ i_z * cap_order + k ], for k = 0 , ... , p-1, is the k-th order Taylor coefficient corresponding to z. Output: taylor [ i_z * cap_order + k ], for k = p, ... , q, is the k-th order Taylor coefficient corresponding to z.

Checked Assertions

• NumArg(op) == 2
