The initial number of extra
rows to allow for in
the matrix, including cuts. If rows are to be added to the matrix, then, for maximum efficiency,
space should be reserved for the rows before the matrix is input by setting the
EXTRAROWS
control. If this is not done, resizing will occur automatically, but more space may be allocated
than the user actually requires. The space allowed for cuts is equal to the number of extra rows
remaining after rows have been added but before the global optimization starts.
EXTRAROWS
is set automatically by the optimizer when the matrix is first input to allow space for cuts, but if
you add rows, this automatic setting will not be updated. So if you wish cuts, either automatic cuts
or user cuts, to be added to the matrix and you are adding rows,
EXTRAROWS must be set
before the matrix is first input, to allow space both for the cuts and any extra rows that you wish
to add.
