I understand that you want to generate Word Embeddings for BERT Model using MATLAB. To achieve this, you can use the "encode()" function, implemented similar to your own implementation.
[net,tokenizer] = bert;
str = "Bidirectional Encoder Representations from Transformers";
words = encode(tokenizer,str);
In case of BERT, "embedding" and "encoding" can be used interchangeably. Further, you can use the "decode()" function to decode the "encodings".
Kindly refer to the documentation below to know more on these functions:
Kindly note that using "bert" model in MATLAB requires the Text Analytics Toolbox.
Hope this helps
