Generate DICOM file sequence from Matlab

I am trying to generate a sequence of images as DICOM file from matlab, to be used later by other DICOM viewers.
The basic commands are
for j=1:20
image=uint8(2^8*rand(512,512));
dicomwrite(image, ['d:\test\c',num2str(j),'.dcm']);
end
I cannot import metadata from other DICOM files, to be used as a model.
Which parameters of metadata I should manually edit in order to have a sequence that could be seen as a 3D and/or slices by other DICOM viewer?
Because with DICOM viewer I sees the files as as a sequence of images, but I cannot make slices or 3d visualization

I don't have enough experience with radiant to be able to tell you. I do notice that you probably have a typo in your code:
info.InstanceNumber=i;%j is the loop iterator
I would advise you to avoid i and j as loop iterators, because they could potentially clash with the imaginary units 1i and 1j.

Yes this SeriesInstanceUID and StudyInstanceUID solved my problem.
I think to get 3D volume you may need other parameters like voxel 3D info.
info.SeriesNumber=SN;
info.AcquisitionNumber=SN;
info.StudyDate=today;
info.StudyID=num2str(SN);
info.PatientID=num2str(SN);
info.PatientPosition='HFS';
info.AccessionNumber=num2str(SN);
info.StudyDescription=['StudyMAT' num2str(SN)];
info.SeriesDescription=['StudyMAT' num2str(SN)];
info.Manufacturer='Matlab Convert';
info.SliceThickness=volscale(3);
info.PixelSpacing=volscale(1:2);
info.SliceLocation=0;
info.SeriesInstanceUID = uid1;
info.StudyInstanceUID = uid2;
info.InstanceNumber = slicenum;
info.SliceLocation = info.SliceLocation+volscale(3);
