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?

Strong recommendation: Don't do it.
You'll be stuck to make any program downstream with variable name defined by a string.

" this is very basic..."
and the answer is also very basic: dynamically naming variables is one way that beginners force themselves into writing slow, complex, obfuscated, buggy, hard-to-debug code:

"... but I could not get the answer from previous posts"
I am very surprised that you could not find any information on this, expecially considering how this topic has been discussed thousands of times on this forum (I have probably read most of the related threads).

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
