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 $x$,
u0 numeric value of $u$
A a place where the result will be stored.
