MATLAB: How to add/append column in an array in a for loop

arrayloopMATLABmatrix

Hello, I want to get the array [25 25 25 25 25] as the end value of Batt. However, the loop overwrites and I get [25 25 25]. I can't seem to figure out how to append the n_EVs(2) from the next column.
n_AGs = 2;
n_EVs = [2 3];
for j=1:n_AGs
    Batt(1,1:n_EVs(j)) = 25;
end
I specifically want to take the value of n_EVs from the array at each iteration and append the Batt at each iteration. For example:
In the first iteration it should give [25 25]. The second iteration should give [25 25 25 25 25] after appending [0 0 25 25 25] to [25 25].
Would appreciate any help. Best!

Does this do what you want:
n_EVs = [2 3];
n_AGs = length(n_EVs)
Batt = [];
for k = 1 : n_AGs
    Batt = [Batt, 25 * ones(1, n_EVs(k))]
end
Output:
n_AGs =
2
Batt =
25 25
Batt =
25 25 25 25 25
And for n_EVs = [2, 3, 5] it gives:
Batt =
25 25
Batt =
25 25 25 25 25
Batt =
25 25 25 25 25 25 25 25 25 25
