| | ~vari () |
| | Throw an illegal argument exception.
|
| |
| virtual void | init_dependent () |
| | Initialize the adjoint for this (dependent) variable to 1.

| |
| virtual void | set_zero_adjoint () |
| | Set the adjoint value of this variable to 0.
|
| |
| | chainable () |
| | Construct a chainable object.
|
| |
| | ~chainable () |
| | Chainables are not destructible and should go on the function call stack or be allocated with operator new.

|
| |
| const double | val_ |
| | The value of this variable.
|
| |
| double | adj_ |
| | The adjoint of this variable, which is the partial derivative of this variable with respect to the root variable.
