Cplex.GetObjSA Method (Double[], Double[], ILPMatrix, Int32, Int32)

Computes and returns sensitivity analysis for objective coefficients of the variables corresponding to a range of num consecutive columns of the specified LP matrix.

public virtual void GetObjSA(
   double[] lower,
   double[] upper,
   ILPMatrix matrix,
   int start,
   int num
);

Parameters

lower
lower[j] will contain the lowest value to which the objective coefficient of the variable corresponding to column j+start of matrix that can be set, without affecting the optimality of the basis. If this information is not required, null may be passed. Otherwise, the array must have at least length num.
upper
upper[j] will contain the highest value to which the objective coefficient of the variable corresponding to column j+start of matrix that can be set, without affecting the optimality of the basis. If this information is not required, null may be passed. Otherwise, the array must have at least length num.
matrix
The LP matrix which contains the column for which objective sensitivity analysis is to be returned.
start
The index of the first column of matrix for which to return objective sensitivity analysis information.
num
The number of consecutive columns of matrix for which to return objective sensitivity analysis.
