Specify descriptive channel name
Note: You cannot use the legacy interface on 64-bit MATLAB®. See About the Session-Based Interface to acquire and generate data on a 64-bit MATLAB.
ChannelName specifies a descriptive name
for a hardware channel. If a channel name is defined, then you can
reference that channel by its name. If a channel name is not defined,
then the channel must be referenced by its index. Channel names are
not required to be unique.
You can also define descriptive channel names when channels
are added to a device object with the
AI, AO, per channel
Read-only when running
The default value is an empty string. To reference a channel by name, it must contain only letters, numbers, and underscores and must begin with a letter.
Create the analog input object
ai for a sound
card and add two channels to it.
ai = analoginput('winsound'); addchannel(ai,1:2);
To assign a descriptive name to the first channel contained
Chan1 = ai.Channel(1) Chan1.ChannelName = 'Joe'
You can now reference this channel by name instead of by index.
ai.Joe.Units = 'Decibels'
