Question

I'm trying to solve this with matlab, currently my script for this is:

A = [ -7 -5 7 9 -2 -7 3; 4 -10 4 -10 6 0 4; -10 -8 -4 -1 6 -1 5];
b = [ -2 ; -2 ; -13 ];

and with a general solution input,

[x]=linprog(c,[ ],[ ],A,b,zeros(6,1),[ ])

However, I've only seen these problems where there is a C matrix involved also. Could you help confirm or help calculate how to find this third matrix involved in the linear program?
