In this paper, we propose a method to generalize Strang's circulant preconditioner for arbitrary n-by-n matrices A,,. The 181th column of our circulant preconditioner S,, is equal to the 151 th column of the given matrix A,,. Thus if A,, is a square Toeplitz matrix, then S,, is just the Strang circu
