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
