Virtual base class for defining 2D implicit equations.

Member Function Documentation

virtual jFlt j2DImplicit::f( jFlt, jFlt ) = 0 [pure virtual]

Returns the evaluation of the implicit equation at the location passed as the parameter.

virtual jFlt j2DImplicit::dfdx( jFlt x, jFlt y, jFlt d=0.001 ) [virtual]

Returns the derivative wrt x of the implicit equation at the location passed as the parameter. This function is of course not called if a root finder which does not need it is being used.

virtual jFlt j2DImplicit::dfdy( jFlt x, jFlt y, jFlt d=0.001 ) [virtual]

Returns the derivative wrt y of the implicit equation at the location passed as the parameter. This function is of course not called if a root finder which does not need it is being used.

virtual jFlt j2DImplicit::d2fdxy( jFlt x, jFlt y, jFlt d=0.001 ) [virtual]

Returns the second order derivative.
