[spd,S] = MeasMonSpd
(window, settings, [S], [syncMode], [whichMeterType], [bitsppClut])
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:
1 - Use PR650 (default)
2 - Use CVI
10/26/93 dhb Wrote it based on ccc code.
11/12/93 dhb Modified to use SetColor
8/11/94 dhb Sync mode.
8/15/94 dhb Sync mode as argument, allow S to be  for default.
4/12/97 dhb New toolbox compatibility, take window and bits args.
8/26/97 dhb pbe Add noMeterAvail arg.
4/7/99 dhb Add argument for radius board. Compact default arg code.
8/14/00 dhb Call to CMETER('SetParams
') conditional on OS9.
8/20/00 dhb Remove bits arg to SetColor
8/21/00 dhb Remove dependence on RADIUS flag. This is now handled inside of SetColor
dhb Change calling conventions to remove unused args.
9/14/00 dhb Sync mode is not actually used. Arg still passed for backwards compat.
2/27/02 dhb Change noMeterAvail to whichMeterType.
8/19/12 mk Rewrite g_usebitspp path to use PTB imaging pipeline for higher robustness
and to support more display devices.
