Constructor & Destructor Documentation

flair::filter::EulerDerivative::EulerDerivative ( const core::IODevice parent,
const gui::LayoutPosition position,
std::string  name,
const core::Matrix init_value = NULL 


Construct an EulerDerivative at given position.
After calling this function, position will be deleted as it is no longer usefull.
The filter is automatically updated when parent's IODevice::ProcessUpdate is called.
The optional init_value parameters allow to specify the size of the input datas and output inital values. If unspecified, a 1*1 size is used, and values are initialized with 0.
