void PLearn::ExpVariable::bprop (   )  [virtual]

Implements PLearn::Variable. Definition at line 76 of file ExpVariable.cc. References PLearn::Variable::nelems().

void PLearn::ExpVariable::fprop (   )  [virtual]

compute output given input Implements PLearn::Variable. Definition at line 69 of file ExpVariable.cc. References PLearn::Variable::nelems(), and PLearn::safeexp().

PLearn::ExpVariable::PLEARN_DECLARE_OBJECT (  ExpVariable   )

void PLearn::ExpVariable::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 59 of file ExpVariable.cc. References PLearn::Var::length(), and PLearn::Var::width().

void PLearn::ExpVariable::rfprop (   )  [virtual]

Reimplemented from PLearn::Variable. Definition at line 102 of file ExpVariable.cc. References PLearn::TVec< T >::length(), PLearn::Variable::nelems(), and PLearn::UnaryVariable::resizeRValue().

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

Incorrect! Reimplemented from PLearn::Variable. Definition at line 95 of file ExpVariable.cc.
