flip(Module,Module) -- matrix of commutativity of tensor product

Synopsis:

Function: flip

Input:

an instance of class Module.

Output:

an instance of class Matrix.

flip(F,G) -- yields the matrix representing the map F ** G --> G ** F.

Code:

     -- ../../../Macaulay2/m2/matrix1.m2:355-357
     flip(Module,Module) := Matrix => (F,G) -> (
          sendgg(ggPush F, ggPush G, ggflip);
          getMatrix ring F)
