In [[numerical analysis]], the '''Alternating Direction Implicit (ADI) method''' is a [[finite difference]] method for solving [[Parabolic partial differential equation|parabolic]], [[Hyperbolic partial differential equation|hyperbolic]] and [[Elliptic partial differential equation|elliptic]] partial differential equations.<ref>{{Citation | doi=10.1137/0103003 | last1=Peaceman | first1=D.

It is an example of an ''[[operator splitting'']] method.<ref>*{{Cite book | last1=Press | first1=WH | last2=Teukolsky | first2=SA | last3=Vetterling | first3=WT | last4=Flannery | first4=BP | year=2007 | title=Numerical Recipes: The Art of Scientific Computing | edition=3rd | publisher=Cambridge University Press | publication-place=New York | isbn=978-0-521-88068-8 | chapter=Section 20.3.3.
