Predict, Forward and Backward methods of lstmLayer in Neural Network Toolbox

In the Neural Network Toolbox could somebody please give the definition of these three functions or any rough idea about how they are defined and few equations so I can get an idea how to create my custom Layer based on that since I want to create a layer almost similar to LSTMlayer definition only with slight variations.

using MATLAB2018a.

hello dear .Thank you for your help. But boldly, I want to run this code inside MATLAB 2014. What command or function should I add to it? Because my laptop model is low and hangs by installing a higher version.

Hello . I hope you have a good day. I sent the article to your service. I implemented the coding part in the MATLAB software, but to implement my network, two lines of setlayers, training MATLAB 2014 give me an error. What other function do you think I should replace? Do you think the codes I wrote are correct?( I used gait-in-neurodegenerative-disease-database in physionet website.) Thanks a lot
