Dear sir, I want to know the limits of a large scale linear programming problem that can be solved using MATLAB(i.e., no.of constraints, no.of variables, etc).

There are essentially NO hard limits.

There will be soft limits, in the sense that your machine may take a long time to solve some problem. What is a long time? Well, partly, that depends on your definition of long. How tolerant are you?

The time used will be dependent on sooooo many things too. For example, the number of variables, the sparsity of your problem, the number of constraints, what kind of hard disk you have, how much RAM is installed, 64 versus 32 bit MATLAB, how many CPUs are available, what CPU you have, etc. And of course, the limits to your code will depend on what else is running on that machine. If you are off surfing the web, reading your mail, or playing a game on the side while MATLAB runs, those things will take up CPU time and memory away from MATLAB.

How much memory does your 64 bit machine have and how sparse are your constraints?
