add variable to array sequentially inside loop in matlab

You can use the following code snippet in MATLAB to add variables to an array sequentially inside a loop:

main.m
% Initializing the array
my_array = [];

% Loop to add variables sequentially
for i = 1:num_elements
    current_var = some_function(i); % Replace some_function with the function that produces variables you want to add
    my_array(end+1) = current_var;
end

In this code, my_array is initialized as an empty array. Inside the loop, the some_function is called to produce a variable current_var that is then added to the end of my_array. The end+1 index in my_array(end+1) adds the variable to the end position of the array, hence enabling sequential addition of variables.

You can change num_elements to the number of elements that you want to add to the array.
