GMRES with matvec for apply and preconditioner

Hi,
I want to use GMRES with a preconditioner. Both the matrix apply and preconditioner have routines for apply that need information passed in. How do I get gmres to take this. It is currently unhappy with the following: x1 = gmres(@applyA,b,[],tol,maxit,@applyPre,[],[],infoA,infoPre); where infoA is the information needed by applyA to apply A and infoPre is the information needed to apply the preconditioner via applyPre.
