The only solution is to upgrade to R2018a or later.

MATLAB: Error Combining two pixelLabelImageDatastores or randomPatchExtractionDatastores

The error "Duplicate table variable name:" w.r.t combining certain datastores is a known issue and it might be addressed in the future releases.

In order to get the similar behaviour of combine (like that of imageDatastore or pixelLabelDatastore) the workaround would be that you'll need to put the output in a cell by using transform on your pixelLabelImageDatastore.

dataSetDir = fullfile(toolboxdir('vision'),'visiondata','triangleImages');
imageDir = fullfile(dataSetDir,'trainingImages');
labelDir = fullfile(dataSetDir,'trainingLabels');
imds1 = imageDatastore(imageDir);
imds2 = imageDatastore(imageDir);
classNames = ["triangle","background"];
labelIDs   = [255 0];
pxds1 = pixelLabelDatastore(labelDir,classNames,labelIDs);
pxds2 = pixelLabelDatastore(labelDir,classNames,labelIDs);
pids1 = pixelLabelImageDatastore(imds1,pxds1);
pids2 = pixelLabelImageDatastore(imds2,pxds2);
imdsc = combine(imds1,imds2);
pxdsc = combine(pxds1,pxds2);
tpids1 = transform(pids1, @(x){x});
tpids2 = transform(pids2, @(x){x});
pidsc = combine(pids1,pids2);
tpidsc = combine(tpids1,tpids2);
%% Check the behaviour of combine for each type of datastore
read(imds1)
read(imdsc)
read(pxds1)
read(pxdsc)
read(pids1)
read(tpids1)
read(tpidsc)

MATLAB: Undefined function ‘imageDatastore’ for input arguments of type ‘char’.

imageDatastore objects were introduced in R2015b, but imageDatastore() did not become a callable function until R2016a.
