This is the only sane thing to do, otherwise we have two objects referencing the same memory and then we have issues of ownership. In other words, which of the vectors is now responsible for managing and freeing that memory and what happens to the other vector if that memory is released?
PMT vectors知道自己的长度,所以实际上长度值其实也不那么必要(废话好多,神烦)。。。metadata是一个PMT字典,而data是PMT类型的向量,向量元素的类型均是一致的,比如bytes、floats或者complex等。 最后,当PDU Message准备好之后,该block调用gr::block::tagged_stream_to_pdu_impl::send_message方法: void tagged_stream...
It's not just an UBSan warning.sample_motifs()is essentially broken, and likely so are some other functions that take optional integer vectors. Inrinterface.c, I see this: if (!Rf_isNull(sample)) { R_SEXP_to_vector_int_copy(sample, &c_sample); IGRAPH_FINALLY(igraph_vector_int_destro...
Here we propose a further augmentation to the MPNN architecture by considering a more general form of the MPNN message summation step (Eq.1). Using simple summation to convert an unknown cardinality set of vectors into a single vector is hypothetically an expressive bottleneck. Potential better way...

The bond-level features are concatenated with the bond feature vectors before the D-MPNN, such that they are used during message-passing. Alternatively, the user can overwrite the default bond features with the custom features using the option --overwrite_default_bond_features.Similar to molecule-...
The CSI uncertainty is incorporated according to 𝐡̂=𝐡+𝐞h^=h+e, where 𝐡h and 𝐡̂h^ are the true channel vector and estimated channel vectors, respectively. The channel error 𝐞∼𝒞𝒩(0,𝜉2𝐈)e∼CN0,ξ2I with the error variance 𝜉2ξ2. Figure 5 considers...
I have a C code which works in much the same way, but without the classes (the C syntax is bit different mainly because of the arrays vs. vectors). 123456789101112131415 double objective(unsigned n, const double *x, double *grad, void *data) { // ... compute some stuff return 1.234...
