PLearn::HardSlopeVariable::PLEARN_DECLARE_OBJECT (  HardSlopeVariable   )

void PLearn::HardSlopeVariable::recomputeSize (  int &  l, int &  w )  const [virtual]

Recomputes the length l and width w that this variable should have, according to its parent variables. This is used for ex. by sizeprop() The default version stupidly returns the current dimensions, so make sure to overload it in subclasses if this is not appropriate. Reimplemented from PLearn::Variable. Definition at line 65 of file HardSlopeVariable.cc. References PLearn::TVec< Var >::length(), PLERROR, and PLearn::TVec< Var >::size().

void PLearn::HardSlopeVariable::symbolicBprop (   )  [virtual]

compute a piece of new Var graph that represents the symbolic derivative of this Var Reimplemented from PLearn::Variable. Definition at line 144 of file HardSlopeVariable.cc. References PLERROR.
