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 MatrixInverseVariable.cc. References PLearn::Var::length(), and PLearn::Var::width(). |
