I’m trying to make a square table (width = height) for an interaction matrix in the graphing calculator, and I want it to vary in scale based on another variable (n_{odes}.length), while still being able to edit the table directly. Is this possible in the calculator itself, or do I have to leave it as a standard flat list?
Can you share a link for something you may have started? I think what you’re describing is possible, but it would be helpful to be particularly specific about your table(s).
Specifically, do you mean a table in the graph’s expression list, a table component, and/or a table created in the graph space? And, if more than one of these, in which do you need to be “able to edit the table directly”?
Oh, sorry! It did slip my mind that a link would be helpful. Markov Chains | Desmos
The c_onnections variable is a placeholder for the table. I’m hoping to make each row/column pair represent a “current node” and what percentage of its population goes to the “next node”.
I want to edit it in the expression list, although if that’s not possible, I have considered making it part of the graph.
2 things.
1.Desmos does have a matrix calculator, but I think you don’t want to simulate it manually
2. I can’t figure out how to get it to display horizontally…
My mathematical background does not include Markov chains, though I’m sure there are folks that could give more specific help in that regard (e.g. maybe recursive formulas could be helpful?).
Regarding tables though, you cannot dynamically change the width of an expression list table (or if you were using Activity Builder the table component). Instead of defining a list first (i.e. c_onnections), you can manually fill the table and reference that like a list. You would not be able to update it with actions and would need to be manually updated for any changes.
You could fake a table in the graph that changes dynamically. A grid of points using list comprehension is fairly simple.
Thank you! Yeah, I figure I’ll fake a table in the graph. At least I know the calculator’s limits now.
Knew it! I just couldn’t be sure.
