[spd,S] = MeasMonSpd(window, settings, [S], [syncMode], [whichMeterType], [theClut])

Measure the Spd of a series of monitor settings.

This routine is specific to go with CalibrateMon,
as it depends on the action of SetMon.

If whichMeterType is passed and set to 0, then the routine
returns random spectra. This is useful for testing when
you don’t have a meter.

Other valid types: See list in ‘help CMCheckInit’ for various Photo Research
PR-xxx colormeters.
