Detailed Description

Class representing a differentiable function of two variables $f(x,u)$.

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 ).


Member Function Documentation

virtual void diffbifn::dfdx_cond ( const vec &  x0,
const vec &  u0,
mat &  A,
bool  full = true 
) [inline, virtual]

Evaluates $A=\frac{d}{dx}f(x,u)|_{x0,u0}$ and writes result into A .

Parameters:
full denotes that even unchanged entries are to be rewritten. When, false only the changed elements are computed.

Reimplemented in bilinfn.

virtual void diffbifn::dfdu_cond ( const vec &  x0,
const vec &  u0,
mat &  A,
bool  full = true 
) [inline, virtual]

Evaluates $A=\frac{d}{du}f(x,u)|_{x0,u0}$ and writes result into A .

Parameters:
full denotes that even unchanged entries are to be rewritten. When, false only the changed elements are computed.

Reimplemented in bilinfn.
