putsample - Immediately output one sample

Syntax

putsample(obj,data)

Arguments

`obj`	An analog output object.
`data`	The data to be queued in the engine.

Description

putsample(obj,data) immediately outputs the row vector data, which consists of one sample for each channel contained by obj.

Remarks

Using putsample is a good way to test your analog output configuration. Additionally:

putsample does not store samples in the data acquisition engine.
putsample can be executed at any time after channels have been added to obj.
putsample is not supported for sound cards.

Note Refer to the Vendor Limitations section before you access National Instruments^® devices with the NI-DAQmx adaptor simultaneously from multiple applications.

Examples

Create the analog output object ao for a National Instruments board and add two hardware channels to it.

ao = analogoutput('nidaq','Dev1');
ch = addchannel(ao,0:1);

To call putsample for ao:

putsample(ao,[1 1])
