How to edit table lists?

[sunnyandshivcodebros]

I’m making some math blocks, and some of them relate to matrices. I don’t know how to replace a value in a table, could you please help me?

My project’s link is https://snap.berkeley.edu/project?username=sunnyandshivcodebros&projectname=Math%20Blocks%201%2e0 Please help me.

Try:

replace item (x :: variables) of (item (y :: variables) of (table)) with [thing]

I have implemented my own matrices library (I can share the link if you want), and one thing that really helped was hyperblocks (operators and other reporters take lists and combine them):

This meant that I didn't have to write an addition primitive:

If you'd like some advice on how the library should work, I'd be happy to help.
