Arguments
|
x
|
stochastic variable
|
|
c
|
stochastic linear constraint
|
|
t
|
stage number t beloning to {1..T}, where T is the number of stages
|
|

Return value
realized value of stochastic entity in scenario tree
Further information
1. The stage of rn/re/x/c cannot be greater than t.
2. If x is fixed, its fixed value is returned.
3. speval(.) returns fixed or expected value of stochastic entity depending on its.
4. speval(.,t,n) returns realized value of stochastic entity at the nth node in the tth stage.
5. speval(.,s) returns realized value of stochastic entity in the sth scenario.
