matlab.io.fits.getEqColType

Get column data type, repeat value, width

Syntax

[dtype,repeat,width] = getEqColType(fptr,colnum)

Description

[dtype,repeat,width] = getEqColType(fptr,colnum) returns the equivalent data type needed to store the scaled column data type, the vector repeat value, and the width in bytes of a column in an ASCII or binary table.

This function corresponds to the fits_get_eqcoltypell (ffeqtyll) 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.getEqColType(fptr,5);
fits.closeFile(fptr);
