Re: how to do linear programming in mpitb\octave

[Jack Franklin]

Thanks, 

But the example over there is too simple.

I need to do programming in MPITB\octave in order to implement some
algorithm to solve mixed linear 
programming.

I need to call GLPK package from octave.

But, I do not know how to describe the linear programming problem components
for GLPK .

For example, how to describe AX + BY - CZ <=b, and  (AX − BY + CZ) >=  (EX
− FY + DZ) in octave
here, the A,B,C, E,F,D are all large matrix with different dimensions. 

so that I can call GLPK to solve them ?.

here , X,Y,Z are decision variables and  A,B,C, D,E,F are  coefficient
matrices.

I have got some simple examples about GLPK programming but they are very
simple and the matrices are
input by hand.

My LP problem is very large and how can I describe them in octave more
effciently?


Thanks,

Jack
