Sourceval set_row_bnds : prob -> int -> Bnd.t -> float -> float -> unit

set_row_bnds prob i bnd lb ub sets bounds of i-th row (constraint). * If the row is not lower (upper) bounded, lb (ub) is just ignored. * If the row is equality constraint (Bnd.FX), * only lb is used and ub is ignored.

Sourceval set_col_bnds : prob -> int -> Bnd.t -> float -> float -> unit

set_col_bnds prob j bnd lb ub sets bounds of j-th col (variable). * If the col is not lower (upper) bounded, lb (ub) is just ignored. * If the col is equality constraint (Bnd.FX), * only lb is used and ub is ignored.

Sourceval set_obj_coef : prob -> int -> float -> unit

set_obj_coef prob j sets the objective coefficient * at j-th col (variable)

Sourceval set_mat_row : prob -> int -> int -> unit Ctypes_static.ptr -> unit Ctypes_static.ptr -> unit

set_mat_row prob i len indices vals sets the i-th row of constraint matrix.

Sourceval set_mat_col : prob -> int -> int -> unit Ctypes_static.ptr -> unit Ctypes_static.ptr -> unit

set_mat_col prob j len indices vals sets the j-th column of constraint matrix.

Sourceval load_matrix : prob -> int -> unit Ctypes_static.ptr -> unit Ctypes_static.ptr -> unit Ctypes_static.ptr -> unit

load_matrix prob ne ia ja ar sets the constraint matrix. * The matrix is represented as an sparce matrix. * for k=1 .. ne, value ark is set at (iak, jak) element.
