I am using "intlinprog" to solve a system of linear equations. The "f" matrix is a 1x180 matrix. Can intlinprog process large matrices like this? I have 12 unknowns with 7 equality constraint equations.

Very sorry, I meant to say 180 unknowns and 28 constraints. I made a mistake while creating the Aeq matrix and it now outputs one solution. Is there a way to check all answers matlab comes up with, not just the optimal point? Thank you very much.

The Display property of intlinprog() is already set to 'iter', which mean it already displays the result of each iteration by default. I am not sure whether you will be able to access any more information than that but you can give this link a try: https://www.mathworks.com/help/matlab/math/output-functions.html#bsgpq6q-31

If you are referring to intermediate feasible solutions you can use the built-in OutputFcn savemilpsolutions:
intlinprog OutputFcns
Just a warning: if there is no objective function for the problem (or it is all zero), then as soon as intlinprog finds any integer feasible solution, it will stop.
