inline

Zero order forward mode implementation of op = StvvOp.

The C++ source code corresponding to this operation is

     v[x] = y

where v is a VecAD<Base> vector, x is an AD<Base> object, and y is AD<Base> or Base objects. We define the index corresponding to v[x] by

     i_v_x = index_by_ind[ arg[0] + i_vec ]

where i_vec is defined under the heading arg[1] below:

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

i_z	is the index corresponding to the previous variable on the tape (only used for error checking).
arg	arg[0] is the offset of this VecAD vector relative to the beginning of the isvar_by_ind and index_by_ind arrays. arg[1] If this is a StppOp or StpvOp operation (if x is a parameter), i_vec is defined by i_vec = arg[1] If this is a StvpOp or StvvOp operation (if x is a variable), i_vec is defined by i_vec = floor( taylor[ arg[1] * cap_order + 0 ] ) where floor(c) is the greatest integer less that or equal c. arg[2] index corresponding to the third operand for this operator; i.e. the index corresponding to y.
num_par	is the total number of parameters on the tape (only used for error checking).
cap_order	number of columns in the matrix containing the Taylor coefficients.
taylor	In StvpOp and StvvOp cases, `<taylor[ arg[1] * cap_order + 0 ]` is used to compute the index in the definition of i_vec above.
isvar_by_ind	If y is a varable (StpvOp and StvvOp cases), `isvar_by_ind[ arg[0] + i_vec ]` is set to true. Otherwise y is a paraemter (StppOp and StvpOp cases) and `isvar_by_ind[ arg[0] + i_vec ]` is set to false.
index_by_ind	`index_by_ind[ arg[0] - 1 ]` is the number of elements in the user vector containing this element. The value `index_by_ind[ arg[0] + i_vec]` is set equal to arg[2].

Check User Errors

Check that the index is with in range; i.e. i_vec < index_by_ind[ arg[0] - 1 ] Note that, if x is a parameter, the corresponding vector index and it does not change. In this case, the error above should be detected during tape recording.
