Member Function Documentation

void bilinfn::dfdx_cond	(	const vec &	x0,
		const vec &	u0,
		mat &	A,
		bool	full
	)			`[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.
	x0	numeric value of ,
	u0	numeric value of
	A	a place where the result will be stored.

Reimplemented from diffbifn.

void 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.
