) | [inline] |
Compute zero order forward mode Taylor coefficient for result of op = SinOp.
The C++ source code corresponding to this operation is
z = sin(x)
The auxillary result is
y = cos(x)
The value of y is computed along with the value of z.
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 . |
i_z | variable index corresponding to the last (primary) result for this operation; i.e. the row index in taylor corresponding to z. The auxillary result is called y and has index i_z - 1. |
i_x | variable index corresponding to the argument for this operator; i.e. the row index in taylor corresponding to x. |
nc_taylor | number of colums in the matrix containing all the Taylor coefficients. |
taylor | Input: taylor [ i_x * nc_taylor + 0 ] is the zero order Taylor coefficient corresponding to x. Output: taylor [ i_z * nc_taylor + 0 ] is the zero order Taylor coefficient corresponding to z. Output: taylor [ ( i_z - 1 ) * nc_taylor + j ] is the j-th order Taylor coefficient corresponding to the autillary result y. |
