MATLAB: How to rename an existing structure A by assigning it a name stored in a string

renamestructures

Sorry, this is very basic, but I could not get the answer from previous posts:

How to rename an existing structure A by assigning it a name new_name stored in a string name_string?

A=struct

new_name=”name_string”

How can I rename A to name_string?

Best Answer

You can use assignin for that purpose

A = struct('X',1,'Y',2)
new_name='B';
assignin('base',new_name,A);
disp(B)

B =

struct with fields:

X: 1

Y: 2

MATLAB: Is it possible to extract all fields from a structure automatically

You seem intent on magically making variables pop into existence in the workspace, so here is probably the least-worst way of doing that. The trick is to change the save command by adding the '-struct' option:

 >> S.name = 'anna';
 >> S.data = 1:3;
 >> save('temp.mat','-struct','S')

and then load it like this:

 >> clear
 >> load('temp.mat')
 >> name
 name = anna
 >> data
 data =
    1   2   3

and you will find all of those variables in your workspace.

MATLAB: Help with If else statements

Your first elseif is always going to be true. Why? Because you are ignoring MATLAB's rules of operator precedence. Check this out:

>> TeamAScore = 5;
>> TeamAScore == 8 || 7
ans =
     1

Does this mean that 5 is equal to either seven or eight? Of course not, we just need to follow the basic operator precedence rules that we were taught in highschool (and shown in the link above), so we know that this code is really equivalent to:

>> (TeamAScore == 8) || 7
ans =
     1
>> 0 || 7
ans =
     1

where seven is true because it is non-zero. When you pay attention to the operator precedence rules then you would probably have written something like this:

>> TeamAScore == 7 || TeamAScore == 8
ans =
     0

Or more compactly:

>> any(TeamAScore == [7,8])
ans =
     0
