add elements to an array during loop in matlab

To add elements to an array during a loop in MATLAB, you can use the indexing operator [] to append new elements to the end of the array. Here's an example code that demonstrates how to add elements to an array during a loop:

main.m
% Create an initial array with one element
myArray = 1;

% Loop 10 times and append a new element to the array each time
for i = 2:11
    % Compute the new element as a function of i
    newElement = i^2;
    
    % Append the new element to the end of the array
    myArray(end+1) = newElement;
end

% View the final array
disp(myArray);

15 lines

In this example, the loop starts at 2 and ends at 11. During each iteration of the loop, a new element is computed and appended to the end of the current array, using the indexing operator [] and the end keyword to specify the end of the array.

Note that the initial array can have any number of elements, and the loop can add as many elements as needed. Additionally, the elements being added do not need to be computed from the loop index - they can be any value or function of other variables in your code.
