changeObjCoefs-methods: Change Column (Variable) Objective Coefficients in the Optimization Problem

Description

Change column (variable) objective coefficients in the optimization problem.

Usage

# S4 method for optObj_clpAPI
changeObjCoefs(lp, j, obj_coef)
# S4 method for optObj_cplexAPI
changeObjCoefs(lp, j, obj_coef)
# S4 method for optObj_glpkAPI
changeObjCoefs(lp, j, obj_coef)
# S4 method for optObj_lpSolveAPI
changeObjCoefs(lp, j, obj_coef)

Arguments

lp
