Public Member Functions

vec eval (const vec &cond)

Evaluates $f(x0,u0)$ (VS: Do we really need common eval? ).

int _dimx () const

virtual void condition (const vec &val)

function substitutes given value into an appropriate position

int dimension () const

access function

virtual string to_string ()

This method returns a basic info about the current instance.

Member Function Documentation

void bdm::bilinfn::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.
	x0	numeric value of ,
	u0	numeric value of
	A	a place where the result will be stored.

Reimplemented from bdm::diffbifn.
