I finally have been getting the oscilloscope feature working in the instrument toolbox. I am running a Tek MDO3104 and am able to manipulate some parameters:
>> get(myScope)
AcquisitionStartDelay = 0
AcquisitionTime = 1.000000e-02
ChannelNames = CH1, CH2, CH3, CH4, MATH, REF1, REF2, REF3, REF4
ChannelsEnabled = CH1, CH2, CH3
Driver = tektronix
DriverDetectionMode = auto
Resource = TCPIP0::10.20.31.58::inst0::INSTR
SingleSweepMode = off
Status = open
Timeout = 10
TriggerMode = auto
TriggerLevel = 4.000000e-02
TriggerSlope = rising
TriggerSource = CH1
WaveformLength = 1000
>> myScope.ChannelsEnabled
ans =
'CH1' 'CH2' 'CH3'
>> disableChannel('CH1') Undefined function 'disableChannel' for input arguments of type 'char'.
Any insight as to why that fails and what I can do about it?
thank you

From my understanding, it seems like you are using the Quick-control oscilloscope object, and are able to connect to the oscilloscope.
I assume that you have looked into the pre-requisites to use the Quick-control oscilloscope in this link: http://www.mathworks.com/help/instrument/using-quick-control-oscilloscope.html#bs6b15j
To disable the channels, use one of the following syntax:
1. Pass the 'myScope' object as an argument:
>> disableChannel(myScope, {'CH1', 'CH2'});
or
2. use the dot notation:
>> myScope.disableChannel({'CH1', 'CH2'});
