 void CppAD::local::conditional_exp_op ( size_t i_z, const addr_t * arg, size_t num_par, const Base * parameter, size_t cap_order )
inline

Shared documentation for conditional expressions (not called).

The C++ source code coresponding to this operation is

```     z = CondExpRel(y_0, y_1, y_2, y_3)
```

where Rel is one of the following: Lt, Le, Eq, Ge, Gt.

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 AD variable index corresponding to the variable z. arg arg[0] is static cast to size_t from the enum type ``` enum CompareOp { CompareLt, CompareLe, CompareEq, CompareGe, CompareGt, CompareNe } ``` for this operation. Note that arg[0] cannot be equal to CompareNe. arg[1] & 1 If this is zero, y_0 is a parameter. Otherwise it is a variable. arg[1] & 2 If this is zero, y_1 is a parameter. Otherwise it is a variable. arg[1] & 4 If this is zero, y_2 is a parameter. Otherwise it is a variable. arg[1] & 8 If this is zero, y_3 is a parameter. Otherwise it is a variable. arg[2 + j ] for j = 0, 1, 2, 3 is the index corresponding to y_j. num_par is the total number of values in the vector parameter. parameter For j = 0, 1, 2, 3, if y_j is a parameter, parameter [ arg[2 + j] ] is its value. cap_order number of columns in the matrix containing the Taylor coefficients.
Checked Assertions
• NumArg(CExpOp) == 6
• NumRes(CExpOp) == 1
• arg[0] < static_cast<size_t> ( CompareNe )
• arg[1] != 0; i.e., not all of y_0, y_1, y_2, y_3 are parameters.
• For j = 0, 1, 2, 3 if y_j is a parameter, arg[2+j] < num_par.
