To add an element to an array in MATLAB, you can use either the end keyword or the index of the last element in the array plus one. Here are some examples:
1. Using the end keyword:
A = [1 2 3];
A(end+1) = 4;
disp(A);
Output:
[1 2 3 4]
2. Using the index of the last element plus one:
B = [5 6 7];
B(length(B)+1) = 8;
disp(B);
Output:
[5 6 7 8]
Note: It's important to make sure that the index you use for adding an element is within the bounds of the array.
