Specify callback function to execute when predefined number of samples is output for each channel group member
Note: You cannot use the legacy interface on 64-bit MATLAB®. See Working with the Session-Based Interface to acquire and generate data on a 64-bit MATLAB.
A samples output event is generated immediately after the number of samples specified by the SamplesOutputFcnCount property is output for each channel group member. This event executes the callback function specified for SamplesOutputFcn.
Use SamplesOutputFcn to trigger an event each time a specified number of samples is output. To process samples at regular time intervals, use the TimerFcn property.
Samples output event information is not stored in the EventLog property. When the callback function is executed, the second argument is a structure containing two fields. The Type field value is set to the string 'SamplesOutput', and the event Data field values are given below.
Data Field Value
The absolute time (as a clock vector) the event occurred.
The output sample number when the event occurred.
