setColsBndsGLPK: Set/Change Column Bounds
Description
This is an advanced version of setColBndGLPK.
Here, j can be an integer vector, lb and ub
can be numeric vectors.Usage
setColsBndsGLPK(lp, j, 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. j
Vector of column numbers.
lb
Vector of lower bounds.
ub
Vector of upper bounds.
type
Vector of variable types (default: NULL).
Details
Interface to the C function setColsBnds which calls the GLPK
function glp_set_col_bnds.
If type is set to NULL, the type of the variables will be estimated.
If lb[i] equals ub[i], variable j[i] is fixed, otherwise double bounded.References
