setRowsBndsGLPK function

Set/Change Row Bounds

This is an advanced version of setRowBndGLPK. Here, i can be an integer vector, lb and ub

can be numeric vectors.

setRowsBndsGLPK(lp, i, lb, ub, type = NULL)

Arguments

• lp: An object of class "glpkPtr" as returned by initProbGLPK. This is basically a pointer to a GLPK problem object.
• i: Vector of row numbers.
• lb: Vector of lower bounds.
• ub: Vector of upper bounds.
• type: Vector of variable types (default: NULL). For possible values, see glpkConstants, section LP/MIP problem object .

Details

Interface to the C function setRowsBnds which calls the GLPK function glp_set_row_bnds.

If type is set to NULL, the type of the variables will be estimated. If lb[j] equals ub[j], variable i[j] is fixed, otherwise double bounded.

Returns

NULL
