| vec | eval (const vec &cond) |
| Evaluates $f(x0,u0)$ (VS: Do we really need common eval? ). | |
| virtual vec | eval (const vec &x0, const vec &u0) |
| Evaluates $f(x0,u0)$. | |
| virtual void | dfdx_cond (const vec &x0, const vec &u0, mat &A, bool full=true) |
Evaluates and writes result into A . | |
| virtual void | dfdu_cond (const vec &x0, const vec &u0, mat &A, bool full=true) |
Evaluates and writes result into A . | |
| diffbifn (const RV rvx0, const RV rvu0) | |
| Default constructor (dimy is not set!). | |
| int | _dimx () const |
| access function | |
| int | _dimu () const |

Protected Attributes | |
| RV | rvx |
| Indentifier of the first rv. | |
| RV | rvu |
| Indentifier of the second rv. | |
| int | dimx |
| cache for rvx.count() | |
| int | dimu |
| cache for rvu.count() | |
| int | dimy |
| Length of the output vector. | |
Function of two variables.
TODO: 1) Technically, it could have a common parent (e.g. fnc ) with other functions. For now, we keep it as it is. 2) It could be generalized into multivariate form, (which was original meaning of fnc ).

| const vec & | u0, | |||
| mat & | A, | |||
| bool | full = true | |||
| ) | [inline, virtual] |
Evaluates
and writes result into A .
| full | denotes that even unchanged entries are to be rewritten. When, false only the changed elements are computed. | |
| x0 | numeric value of $x$, | |
| u0 | numeric value of $u$ | |
| A | a place where the result will be stored. |
