| virtual string | getValString (int col, real val) const |
| returns the string associated with value val for field# col. | |
| virtual string | getString (int row, int col) const |
| returns element as a string, even if value doesn't map to a string, in which case tostring(value) is returned | |

The lists of VMFields are appended upon construction. The case where some VMat may have some fields and others not is handled properly. Definition at line 50 of file ConcatColumnsVMatrix.cc. References array, build_(), and PLearn::TVec< VMat >::size(). |

Should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object.

redefine this in subclasses: call declareOption(...) for each option, and then call inherited::declareOptions(options) ( see the declareOption function further down) ex: static void declareOptions(OptionList& ol) { declareOption(ol, "inputsize", &MyObject::inputsize_, OptionBase::buildoption, "the size of the input\n it must be provided"); declareOption(ol, "weights", &MyObject::weights, OptionBase::learntoption, "the learnt model weights"); inherited::declareOptions(ol); } Reimplemented from PLearn::VMatrix.

returns the dot product between row i1 and row i2 (considering only the inputsize first elements). The default version in VMatrix is somewhat inefficient, as it repeatedly calls get(i,j) The default version in RowBufferedVMatrix is a little better as it buffers the 2 Vecs between calls in case one of them is needed again. But the real strength of this method is for specialised and efficient versions in subbclasses. This method is typically used by SmartKernels so that they can compute kernel values between input samples efficiently. Reimplemented from PLearn::RowBufferedVMatrix.
