where can I see the parameter 'Order' in Cplex class?

for line 69*Use addSOSs to add SOS*, what's the purpose to add SOS in MIP?

if you run mipex3.m, then error will be present

??? Error using ==> mipex3 at 89
No appropriate method, property, or field writeOrder for class Cplex.

what's wrong with it?

thanks a lot.

1. do you mean you want to take a look Order's help document?
2. SOS is a MIP technology, you can go to this link to take a look:
http://publib.boulder.ibm.com/infocenter/cosinfoc/v12r4/topic/ilog.odms.cplex.help/CPLEX/User_manual/topics/discr_optim/sos/uss_usingSOS_1.html
3. how did you run mipex3, you should run mipex3 like:

>> mipex3('r')
Default variable names x1, x2 ... to be created.
MIP Presolve eliminated 1 redundant SOS constraints.
Tried aggregator 1 time.
MIP Presolve eliminated 3 rows and 4 columns.
All rows and columns eliminated.
Presolve time =    0.00 sec.
 
Solution status = integer optimal solution 
Solution value = 56.000000 
Values =
    40
     7
     0
     2
 
Slacks =
    33
    11
     0

or mipex3('c'), mipex3('n')

but when I search cplex.order, No Matches Found,why?

when I run

mipex3('r')

??? Error using ==> mipex3 at 89
No appropriate method, property, or field writeOrder for class Cplex.

Do you know the reason?
