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);
