# ColgenInstance:cg_subproblem_solution(++Value)

Posts new subproblem solution(s) to the colgen instance ColgenInstance.

Value
  Subproblem solution (sp_sol structure) or list of subproblem solutions

## Description

Post subproblem solution(s) corresponding to a column of coefficients for a new master problem variable to the colgen instance `ColgenInstance`. The argument must be a `sp_sol` structure or list of such structures:

          sp_sol(cost, coeff_vars, aux)

where `cost` is the master problem cost function coefficient of the solution, `coeff_vars` is a list of `Id-Val` pairs corresponding to the subproblem variable solution values and identifier of the constraint in which it occurred as an implicit sum term for those subproblem variables with a non-zero solution value. `aux` should contain any problem specific information which is of interest that is not represented uniquely by the cost and objective coefficients.
