fixmipentities

Purpose
Fixes all the MIP entities to the values of the last found MIP solution.
This is useful for finding the reduced costs for the continuous variables after the integer variables have been fixed to their optimal values.
Synopsis
fixmipentities(prob, options)
Arguments
prob 
The current problem.
options 
Options how to fix the MIP entities.
0
If all MIP entities should be rounded to the nearest discrete value in the solution before being fixed.
1
If piecewise linear and general constraints should be kept in the problem with only the non-convex decisions (i.e. which part of a non-convex piecewise linear function or which variable attains a maximum) fixed. Otherwise all variables appearing in piecewise linear or general constraints will be fixed.
Return value
The input argument prob.
