 void CppAD::local::forward2sweep ( const local::player< Base > * play, const size_t q, const size_t r, const size_t n, const size_t numvar, const size_t J, Base * taylor, const bool * cskip_op, const pod_vector< addr_t > & var_by_load_op )

Compute multiple directions forward mode Taylor coefficients.

Template Parameters
 Base The type used during the forward mode computations; i.e., the corresponding recording of operations used the type AD.
Parameters
 q is the order of the Taylor coefficients that are computed during this call; q > 0. r is the number of Taylor coefficients that are computed during this call. n is the number of independent variables on the tape. numvar is the total number of variables on the tape. This is also equal to the number of rows in the matrix taylor; i.e., play->num_var_rec(). play The information stored in play is a recording of the operations corresponding to the function where is the number of independent variables and is the number of dependent variables. J Is the number of columns in the coefficient matrix taylor. This must be greater than or equal one. taylor Input: For i = 1 , ... , numvar-1, taylor[ (J-1)*r*i + i + 0 ] is the zero order Taylor coefficient corresponding to the i-th variable and all directions. For i = 1 , ... , numvar-1, For k = 1 , ... , q-1, ell = 0 , ... , r-1, taylor[ (J-1)*r*i + i + (k-1)*r + ell + 1 ] is the k-th order Taylor coefficient corresponding to the i-th variabel and ell-th direction. Input: For i = 1 , ... , n, ell = 0 , ... , r-1, taylor[ (J-1)*r*i + i + (q-1)*r + ell + 1 ] is the q-th order Taylor coefficient corresponding to the i-th variable and ell-th direction (these are the independent varaibles). Output: For i = n+1 , ... , numvar-1, ell = 0 , ... , r-1, taylor[ (J-1)*r*i + i + (q-1)*r + ell + 1 ] is the q-th order Taylor coefficient corresponding to the i-th variable and ell-th direction. cskip_op Is a vector with size play->num_op_rec(). If cskip_op[i] is true, the operator with index i does not affect any of the dependent variable (given the value of the independent variables). var_by_load_op is a vector with size play->num_load_op_rec(). It is the variable index corresponding to each the load instruction. In the case where the index is zero, the instruction corresponds to a parameter (not variable).
