Hi,

I have used the function Linprog (Large scale_par default) to optimise
the problem with 77 variables, and the result turns well. The solution
is optimised.


The problem is that i dont know if my problem is large scale or medium
scale, so i changed the problem from large scale into medium scale,
and turned on the algorithm simplex.
the command used is as followed :

Code : Sélectionner tout - Visualiser dans une fenêtre à part
1
2
3
 
options=optimset('linprog') 
linprog1=optimset(options,'largescale','off','simplex','on')

Matlab give me the error message as below :

??? This index expression yields only one result.


Error in ==> binary_int1 at 181
[Xopt,cout_total, exitfl, output, lambda]= linprog1(f, A,b, Aeq,
beq,lb,ub);

Question :
I dont what this message means?
does it means that i can optimised by medium scale problem (simplex) ?
