Query: A noncommutative semi-discrete Toda equation and its quasideterminant
  solutions   A noncommutative version of the semi-discrete Toda equation is considered. A
Lax pair and its Darboux transformations and binary Darboux transformations are
found and they are used to construct two families of quasideterminant
solutions.
