You can use cat()
image3d = cat(3, slice1, slice2, slice3, slice4);
or in a loop where you read in each slice
array3d = zeros(rows, columns, numberOfSlices);
for slice = 1 : numberOfSlices
  filename = spritnf('image #%d', slice);
  fullFileName = fullfile(folder, filename);
  if exist(fullFileName, 'file)
    thisSlice = imread(fullFileName);
    array3d(:,:,slice) = thisSlice;
  end
end
or if you don't know the number of slices in advance,
thisSlice = imread(filename);
if slice == 1
  array3d = thisSlice
else
  array3d = cat(3, array3d, thisSlice);
end
