# STSHELL

Creates a new spectral transformation class. This is intended to provide a simple class to use with EPS. You should not use this if you plan to make a complete class.

### Usage

                extern PetscErrorCode (*apply)(void*,Vec,Vec);

                extern PetscErrorCode (*applytrans)(void*,Vec,Vec);

                extern PetscErrorCode (*backtr)(void*,PetscScalar*,PetscScalar*);

                STCreate(comm,&st);

                STSetType(st,STSHELL);

                STShellSetContext(st,ctx);

                STShellSetApply(st,apply);

                STShellSetApplyTranspose(st,applytrans);  (optional)

                STShellSetBackTransform(st,backtr);       (optional)
