Saving workspace variables into one struct
显示 更早的评论
I have a workspace containing
date (178x1 cell)
opposing_team (178x1 double)
team (178x1 double)
win (178x1 double)
I want to merge these variables into 1 struct. I tried using this code here
data = struct('date',{''},'opposing_team',[],'team',[],'win',[]);
but it deletes the data inside it, so when I open the variables it returns with a blank table. How do I create a struct that will keep the data inside? Thanks in advance.

@Adhi Ariawan: do you want a scalar structure containing arrays, or a non-scalar structure containing scalars?

@Adhi Ariawan: "scalar" means that the array has size 1x1:

Here are the two main options. First we will use this fake data:
>> date = num2cell(randi(365,178,1));
>> oppt = rand(178,1);
>> team = rand(178,1);
>> win = rand(178,1);
Non-Scalar structure of with scalar fields:
>> S = struct('date',date,'oppteam',num2cell(oppt),'team',num2cell(team),'win',num2cell(win));
>> size(S)
ans =
178 1
>> S(1)
ans =
scalar structure containing the fields:
date = 25
oppteam = 0.17320
team = 0.82512
win = 0.46835
Scalar structure with non-scalar fields:
>> S = struct('date',{date},'oppteam',oppt,'team',team,'win',win);
>> size(S)
ans =
1 1
>> S.date{1}
ans = 25
>> S.oppteam(1)
ans = 0.17320
>> S.team(1)
ans = 0.82512
>> S.win(1)
ans = 0.46835

@Stephen23 Hello Stephen
I have so many non-scalar structures in my workspace and I want to use the command above without having to writing name by name, can you please advise?
Thanks in advance.

Depending on what their names are and how many other variables there are, you could possibly use SAVE with its -regexp option or something similar. Read the SAVE documentation.
