How to create a matrix for 2D look-up table from 3 vectors

Hello,

I have 3 vectors that depend on time : DCR(t), SOC(t), Temp(t).

Do you guys known from 3 vectors above, how could I do to create the matrix that represent the relationship between these 3 parameters ? I means how could I do to create a 2D look-up table of DCR with breakpoint1 is SOC and breakpoint2 is Temp ?

Thank you for reading my question Looking for your answers.

This looks like a rephrasing of the question you asked two days ago. If you're not looking for a two-keyed hash map, what is it you're looking for? A data structure or a visualization?

If you want a table, you could just do:

table(SOC, Temp, DCR)

If you want a matrix (no headers), you could do:

[SOC, Temp, DCR]

I'm not sure what you mean by breakpoint.
