Hi,
I'm wondering if Clp has a method that can update existing row/column
elements? Like glp_set_mat_row()? Thanks.
I can only find setRow() in cuts but not simplex method. It's unusual that
Clp doesn't provide a replace method for existing row/col.
I know I can use "addRow", build from scratch. But what if I
resize(numOfRows,numOfCols) to initialize the constraint matrix, and then
modify some of them, can I ?

Thanks,
Emer
