It has to be passed across to ClpModel or OsiSolverInterface by addRows, addCol(umn)s or loadProblem.
It may have up to four parts - 1) A matrix of doubles (or strings - see note A) 2) Column information including integer information and names 3) Row information including names 4) Quadratic objective (not implemented - but see A)
This class is meant to make it more efficient to build a model. It is at its most efficient when all additions are done as addRow or as addCol but not mixed. If only 1 and 2 exist then solver.addColumns may be used to pass to solver, if only 1 and 3 exist then solver.addRows may be used. Otherwise solver.loadProblem must be used.
If addRows and addColumns are mixed or if individual elements are set then the speed will drop to some extent and more memory will be used.
It is also possible to iterate over existing elements and to access columns and rows by name. Again each of these use memory and cpu time. However memory is unlikely to be critical as most algorithms will use much more.
Notes: A) Although this could be used to pass nonlinear information around the only use at present is to have named values e.g. value1 which can then be set to a value after model is created. I have no idea whether that could be useful but I thought it might be fun. Quadratic terms are allowed in strings! A solver could try and use this if so - the convention is that 0.5* quadratic is stored
B) This class could be useful for modeling.
