I have a 6x1 struct and want to create a for loop that will cycle through and pull out the name field of the 1x1 struct.
How can I do that? ** I am using R2012a **
I apologize for the strange format, the toolbar at the top of the body is missing and I'm still trying to fix it.

You probably don't need a for loop, you can use the function fieldnames(S) (look at its documentation for more info).
P. S. You can use Alt + Enter to switch between code and plain text modes.

listNames = { YourStructArray.Name };
This will return a cell array of all the names present in the array of structs.
Hope this helps

Hi,
As per my understanding, there is a struct array of dimension 6x1 and you want to use a 'for' loop to cycle through each and pick a certain field.
This can be done using the below mentioned steps:.
  • Initialize a cell array to store the vested fields
  • Loop through each element of the struct array
  • Access the name field using .(dot) operator and store it in the cell array for future use
Please see the below code on how to achieve this:
% Create a 6x1 structure array with a 'name' field
myStruct(1).name = 'Alice';
myStruct(2).name = 'Bob';
myStruct(3).name = 'Charlie';
myStruct(4).name = 'David';
myStruct(5).name = 'Eve';
myStruct(6).name = 'Frank';
% Initialize a cell array to store the names
names = cell(length(myStruct), 1);
% Loop through each element of the structure array
for i = 1:length(myStruct)
% Access the 'name' field of each element
names{i} = myStruct(i).name;
end
% Display the names
disp(names);
The provided code is a sample script that demonstrates how to display the name fields from all the structures within a structure array. You can adjust this code to fit your specific requirements.
I hope this will help!
