program of GLPK in octave

[Jack Franklin]

HI, 

I am doing research in the parallel computing and 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
so that I can call GLPK to solve them ?.

here , X,Y,Z are n-dimension 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
efficiently? 


Thanks, 


Jack
