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.

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:
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.
