Using the Karmarkar method in Scilab

Question

I am new in Scilab, I am planning to use it to do the linear programming. I googled and found this code:

Aeq = [
2 0 6
0 3 5
];
beq = [8;15;30];
c = [30;50];
[xopt]=karmarkar(Aeq,beq,c);

But it seems there is a problem with the karmarkar. Can anyone tell me how to fix my problem? I tried to use help karmarkar because I think it might be the same with Matlab but it didn't work.

Answer 1

The parameters Aeq and beq represent linear equality constraints. Each row of Aeq has the coefficients of an equation, and the corresponding row of beq is the right hand side. Therefore, the number of rows in Aeq and beq must be the same.

Also, the number of rows of c must be equal to the number of variables you have, in this case three.

To summarize: when you have m constraints and n variables, the matrices have the following sizes:

• Aeq is m by n
• beq is m by 1
• c is n by 1

Working example:

Aeq = [
2 0 6
0 3 5
]
beq = [8;15]
c = [30;50;70]
[xopt]=karmarkar(Aeq,beq,c)
