Open Live Script

Open a sample FITS file that has an ASCII table in the fifth HDU. Get information about the second column of the table. Then close the sample file.

import matlab.io.*
fptr = fits.openFile("tst0012.fits");
fits.movAbsHDU(fptr,5);
[ttype,tbcol,tunit,tform,scale,zero,nulstr,tdisp] = fits.getAColParms(fptr,2)
ttype = 
'Mag'

tbcol = 
11

tunit =

  0×0 empty char array

tform = 
'F6.2'

scale = 
1

zero = 
0

nulstr = 
'---.--'

tdisp =

  0×0 empty char array

fits.closeFile(fptr)
