I solved the problem by trying this way :

datasetFolder = ' F:\Datasets\.......; // add the path of your images dataset

imds = imageDatastore(datasetFolder,IncludeSubfolders=true,LabelSource="foldernames");

X=readall(imds);

XTrain = reshape( cat(3,X{:}) , [105,105,1,3410]);

YTrain=imds.Labels;

dsXTrain = arrayDatastore(XTrain,'IterationDimension',4);

dsYTrain = arrayDatastore(YTrain);

dsTrain = combine(dsXTrain,dsYTrain);

and it works perfectly
