Editing FITS file header

How do you change a header keyword and value in a .fits file? Using matlab.io.fits.keyWrite doesn't work for me.

Hey, thank you for that answer! I'll take a closer look. Though it's a shame that MATLAB's built-in fitsio functions don't take care of this. I just wanted to write unsigned 16 bit data to fits. However this requires a header modification and MATLAB makes that hard or impossible.
