This sounds a little like:

Are you able to provide a description of your problem before you
arrived at the situation where reading a long list of matrix
multiplications was the right solution?

We don't endorse using GUI Octave for reasons like this, and because
it's not free.

I would personally would like to know your full problem. It sounds
like premature closure or an X-Y problem. You want to do X and you
have decided that Y is the right way to do it. Now you want us to help
you do Y, but Y looks like a very awkward task. You've prematurely
closed your problem on Y, when there may be a better way to do X
without doing Y at all.
What is your X problem?
