Which paper did you refer to?

I currently want to use matlab to write the grow string method program, I would like to know which paper you refer to write?

I'm interpreting this to mean that you are trying to write a new implementation of the growing string method algorithm in Matlab that behaves similarly to the python implementation in this repository and the implementation in C++. In addition to the source code of these repositories, this paper might help with a conceptual overview at least of the single ended method. I think that paper also cites other papers which may be helpful.
