operator()()

bool ObjectiveDaeDynamic::operator() ( double  time, const std::vector< double > &  x, const std::vector< double > &  xdot, std::vector< double > &  y  )

virtual

residual function returns the Boolean value true if the function residual encountered an error in the input values or false otherwise

Parameters

time	where we are in the integration
x	vector of algebraic and differential unknowns
xdot	vector of derivatives of differential unknowns
y	y = f(xdot,x,t) is the residual to be brought to 0

Implements ObjectiveDae.
