matlab.io.fits.getColType
Get scaled column data type, repeat value, width
Syntax
[dtype,repeat,width] = getColType(fptr,colnum)
Description
[dtype,repeat,width] = getColType(fptr,colnum)
returns
the data type, vector repeat value, and the width in bytes of a column
in an ASCII or binary table.
This function corresponds to the fits_get_coltypell
(ffgtclll)
function in the CFITSIO library C API.
Examples
Get information about the 'FLUX' column in the second HDU.
import matlab.io.* fptr = fits.openFile('tst0012.fits'); fits.movAbsHDU(fptr,2); [dtype,repeat,width] = fits.getColType(fptr,5); fits.closeFile(fptr);
