Create FITS file
fptr = createFile(filename)
fptr = createFile(filename) creates a FITS
file. An error will be returned if the specified file already exists,
unless the filename is prefixed with an exclamation point (!). In
that case CFITSIO will overwrite (delete) any existing file with the
same name.
This function corresponds to the fits_create_file (ffinit) function
in the CFITSIO library C API.
Create a new FITS file.
import matlab.io.* fptr = fits.createFile('myfile.fits'); fits.createImg(fptr,'uint8',[256 512]); fits.closeFile(fptr); fitsdisp('myfile.fits');
