matlab.io.fits.movNamHDU
Move to first HDU having specific type and keyword values
Syntax
movNamHDU(fptr,hdutype,EXTNAME,EXTVER)
Description
movNamHDU(fptr,hdutype,EXTNAME,EXTVER)
moves
to the first HDU which has the specified extension type and EXTNAME
and EXTVER
keyword
values (or HDUNAME
and HDUVER
keywords).
Specify the hdutype
parameter as one of these character vectors or string
scalars.
'IMAGE_HDU' |
'ASCII_TBL' |
'BINARY_TBL' |
'ANY_HDU' |
If hdutype
is 'ANY_HDU'
,
only the EXTNAME
and EXTVER
values
are used to locate the correct extension. If the input value of EXTVER
is
0, then the EXTVER
keyword is ignored and the
first HDU with a matching EXTNAME
(or HDUNAME
)
keyword will be found.
This function corresponds to the fits_movnam_hdu (ffmnhd)
function
in the CFITSIO library C API.
Examples
import matlab.io.* fptr = fits.openFile('tst0012.fits'); fits.movNamHDU(fptr,'IMAGE_HDU','quality',1); fits.closeFile(fptr);
