How to use TTreeReaderArray with RDataFrame::Define

ROOT
1

I have a tree with 3 arrays as below

TTree* t = new TTree("t0", "waves");
Float_t wave[3][1024]{};
t->Branch("t0", wave[0], "t0[1024]/F");
t->Branch("trg1", wave[1], "trg1[1024]/F");
t->Branch("trg2", wave[2], "trg2[1024]/F");

I want to use RDataFrame to analyse the data.
I have write a function which need to input an annay and return a Double_t.

auto timing_t0_lamda = [=](Float_t wave[1024]) -> Double_t {
	return timing_t0(wave, threshold, low, high, false);
};
d.Define("t_t0", timing_t0_lamda, {"t0"});

But the program reports error

Error in <TTreeReaderValueBase::GetBranchDataType()>: Must use TTreeReaderArray to read branch t0: it contains an array or a collection.
Error in <TTreeReaderValueBase::CreateProxy()>: The template argument type T of float* accessing branch t0 (which contains data of type (null)) is not known to ROOT. You will need to create a dictionary for it.
terminate called after throwing an instance of 'std::runtime_error'
  what():  An error was encountered while processing the data. TTreeReader status code is: 6

How should I change my code?
Is there any examples?
