# getsensrng

Purpose
Get sensitivity ranges for objective function coefficients, RHS coefficients, variable upper bounds or variable lower bounds.
Synopsis
`function getsensrng(w:integer, x:mpvar):real`
`function getsensrng(w:integer, c:linctr):real`
Arguments

w | Which information to return. Possible values:
XPRS_UP | Upper sensitivity range
XPRS_DN | Lower sensitivity range
XPRS_UP+XPRS_UBND | Upper sensitivity range of the upper bound of the variable
XPRS_DN+XPRS_UBND | Lower sensitivity range of the upper bound of the variable
XPRS_UP+XPRS_LBND | Upper sensitivity range of the lower bound of the variable
XPRS_DN+XPRS_LBND | Lower sensitivity range of the lower bound of the variable
x | A variable of the problem
c | A constraint of the problem

Return value
Sensivity range information depending on the value of w.
Further information
This function returns sensitivity ranges for RHS coefficients (if used with a constraint); and for objective function coefficients, upper bounds or lower bounds (if used with a variable). getsensrng can be called only if an optimal LP solution is available and the problem is not MIP presolved.
