The snapshot function should return images from both of your cameras. I have no idea if this will work but try
frameLeft = imageLeft;
frameRight = imageRight;
[frameLeftRect, frameRightRect] = ...
rectifyStereoImages(frameLeft, frameRight, stereoParams);
figure;
imshow(stereoAnaglyph(frameLeftRect, frameRightRect));

Posting the discussion in the comment as answer. Feel free to chose it if it solved the problem
1. Call the function "gigecamlist" from the command window. This should return a model if your camera is GigE Vision compliant.
2. Create two camera objects with the "gigecam" function. Use the serial number that was found with the gigecamlist command to seperate them. The call should be something like
cameraLeft = gigecam('serialnumber')
cameraRight = gigecam('serialnumber')
3. Use the "snapshot" function to get the images.
[imageLeft tsLeft] = snapshot(cameraLeft)
[imageRight tsRight] = snapshot(cameraRight)

frameLeft = imageLeft;
frameRight = imageRight;
[frameLeftRect, frameRightRect] = ...
