Compute zero order forward mode Taylor coefficient for result of op = DisOp.
The C++ source code corresponding to this operation is
where f is a piecewise constant function (and it's derivative is always calculated as zero).
- 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 | variable index corresponding to the result for this operation; i.e. the row index in taylor corresponding to z. |
arg | arg[0]
is the index, in the order of the discrete functions defined by the user, for this discrete function.
arg[1] 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 [ arg[1] * 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. |
- Checked Assertions where op is the unary operator with one result:
- NumArg(op) == 2
- NumRes(op) == 1
- arg[1] < i_z
- 0 < nc_taylor
