matlab.io.fits.movAbsHDU

Move to absolute HDU number

Syntax

htype = fits.movAbsHDU(fptr,HDUNUM)


Description

htype = fits.movAbsHDU(fptr,HDUNUM) moves to a specified absolute HDU number (starting with 1 for the primary array) in the FITS file. The possible values for htype are:

'IMAGE_HDU'

'ASCII_TBL'

'BINARY_TBL'

This function corresponds to the fits_move_abs_hdu function in the CFITSIO library C API.

Examples

import matlab.io.*
fptr = fits.openFile('tst0012.fits');
n = fits.getNumHDUs(fptr);
for j = 1:n
    htype = fits.movAbsHDU(fptr,j);
    fprintf('HDU %d:  "%s"\n',j,htype);
end
fits.closeFile(fptr);
