There is only one solution if A is not singular?
Whatever it comes out, I have no control over that.
As an example, you are like asking to find a solution to
4 * x = 2 ----- (1)
With the constraint that the solution is |x| = 1
But the solution is 0.5. There is only one solution.
I do not know how to give you a solution to (1) which comes out
to be satisfy your constraint that is should be something else.
So, I do not understand the question:
"Solve this equation which, has a unique solution, such that the solution
has this property and nothing else"
If your equation does not have a unique solution, then may be
may be there is a way to find all the solutions (which can be
infinite of them), and then pick the one which satisfy your
requirements. I was assuming your are solving Ax=b such that
A is not singular.
