objsa INTARG objsa (lp, begidx, endidx, lower, upper) HPROBLEM lp; INTARG begidx, endidx; LPREALARG lower, upper; This routine need be called only if sensitivity ranges for the objective function coefficients are desired. The argument lp of objsa() must be the value returned by a previous call to loadlp(). The arguments begidx and endidx are used to limit the set of columns (variables) for which the range information is computed. Since range information is not meaningful for NSP, NLP, QP and MIP problems, objsa should not be called for them. objsa returns 0 unless there is an error in its arguments, in which case it returns an integer value indicating the ordinal position of the first argument found to be in error. begidx The first column number (index as in loadlp arguments) for which sensitivity range information should be returned. endidx The last column number (index as in loadlp arguments) for which sensitivity range information should be returned. lower An array of dimension endidx - begidx + 1 where the objective function coefficient lower range values will be returned. upper An array of dimension endidx - begidx + 1 where the objective function coefficient upper range values will be returned. rhssa INTARG rhssa (lp, begidx, endidx, lower, upper) HPROBLEM lp; INTARG begidx, endidx; LPREALARG lower, upper; This routine need be called only if sensitivity ranges for the constraint right hand sides are desired. The argument lp of rhssa() must be the value returned by a previous call to loadlp(). The arguments begidx and endidx are used to limit the set of rows (constraints) for which the range information is computed. Since range information is not meaningful for NSP, NLP, QP and MIP problems, rhssa should not be called for them. rhssa returns 0 unless there is an error in its arguments, in which case it returns an integer value indicating the ordinal position of the first argument found to be in error. begidx The first row number (index as in loadlp arguments) for which sensitivity range information should be returned. endidx The last row number (index as in loadlp arguments) for which sensitivity range information should be returned. lower An array of dimension endidx - begidx + 1 where the constraint right hand side lower range values will be returned. upper An array of dimension endidx - begidx + 1 where the constraint right hand side upper range values will be returned.
