change field position from a structure in matlab

To change the position of a field within a structure in Matlab, you can create a new structure and copy the fields over in the desired order. Here is an example:

main.m
% Sample structure
s.a = 1;
s.b = 2;
s.c = 3;

% Create a new structure with the fields in the desired order
new_s.a = s.a;
new_s.c = s.c;
new_s.b = s.b;

% Replace the original structure with the new structure
s = new_s;

In this example, the fields a, c, b are reordered in the new structure. You can adjust the field order and create new structures as needed.
