Moving Multiple Frames into the Workspace

To move multiple frames of data from the me m ory buffe r into the MATLAB

workspace, use the

getdata function. By default, getdata retrieves the

number of frames specified in the

FramesPerTrigger property but you can

specify any number. See the

getdata reference page for complete information

about this function.

Note When the getdata function moves frames from the memory buffer into

the w orkspace, it removes the frames from the me mory buffer.
