How to write values from workspace dynamically into a table
显示 更早的评论
Hello everyone, I just got started with Matlab(so if this question has already been asked but I oversaw it, just let me know!) I am playing around with a simple model that solves different x in differential equations with different parameter settings. I want to save some of the values from workspace in a table and want to write it into an individual csv. file. I have x(1), x(2) and x(3) which each gets a value for a parameter for their equation, so I give matlab a vector eg: v=[1 1 1]. I also have some parameters that determine what happens with which x and instead of writing it myself manually in the table like f= 1, so something becomes true for x(1), I want Matlab to do it for me.(I also failed at the part to write a table myself for now, by the way).
I want a table with 4 colums where the first columns contains all the variable names, 2-4 should contain x(1), x(2) and x(3) so that I can see which parameter was used for which x. when f=2, I want matlab to write a zero in the column of x(1) and x(3) and a 1 in the column for x(2).
I hope it gets clear what I want to do :(
edit: Sorry for the bad explanation, but I am not allowed to post my original code here due to its a project for university.

What harm is it doing you to leave it as-is? Maybe someone else will find the suggestion from Steven helpful. If this question is deleted, Steven will have to spend time helping that person, instead of them being able to find a suggestion here.
Why did you edit your question?

Here's a small example you could use as a model:
T = array2table(magic(3)) % T is a 3-by-3
T(4, :) = {10, 11, 12} % T is now a 4-by-3
As I created it in this example, the RowNames property of T is empty. But you could set that property then use the RowNames to access and manipulate the table.
T.Properties.RowNames = ["A"; "B"; "C"; "D"]
T{"C", "Var2"} % 9
