SETPREPROC
A = SETPREPROC(A,PREPROC,PARS)
A = SETPREPROC(A,PSTRUCT)
A = SETPREPROC(A)
| Input | |
| A | Datafile |
| PREPROC | String with preprocessing command |
| PARS | Cell array with parameters (default empty) |
| PSTRUCT | Structure array with a set of preprocessing commands |
| Output | |
| A | Datafile |
Resets the structure array of preprocessing commands in A.PREPROC. A.PREPROC(N).PREPROC = PREPROC A.PREPROC(N).PARS = PARS
A call without PREPROC and PARS clears A.PREPROC.
Preprocessing can only be defined for raw datafiles that do not contain datasets. It is an error to define preprocessing for a datafile that points to MAT files. In that case datasets are expected and preprocessing is superfluous. All preprocessing commands are executed just before a DATAFILE is converted into a DATASET.
The first command in the PREPROC field should always be a file read command. The DATAFILE constructor stores by default IMREAD. It is removed by SETPREPROC. Be sure to start a new series of preprocessing commands by a command to read files. The first parameter of this commands should be the filename.
Additional preprocessing commands may be stored by ADDPREPROCC.
