adding multiple arrays in a loop

I would like to run the following loop for N1 = 90 but I am not sure how to set it up so that the arrays stored in matrix V can be added in a loop. Does someone know a better way? Here is my code:

clc;
clear;
%% Signal Setup
% Setting up sampling parameters

Fs = 400e3;           % Sampling rate
T = 1/Fs;           % Sampling period
N = 40000;             % Signal length
t = (0:N-1)*T;        % Time vector

% Wave Setup

f1 = 8000; %Hz
N1 = 1:3;
f2 = (N1)*f1;
V = zeros(size(3,N));

for i = 1:3
    A =(1/N1(i))*sin(2*pi*f2(i)*t); 
    V(i,1:length(t)) = A(:);
end

S = V(1,:) + V(2,:) + V(3,:);
plot(S)
xlim([0 500])

Use

S = sum(V, 1);

So you end up like this:

clc;
clear;
%% Signal Setup
% Setting up sampling parameters

Fs = 400e3;           % Sampling rate
T = 1/Fs;           % Sampling period
N = 40000;             % Signal length
t = (0:N-1)*T;        % Time vector

% Wave Setup

f1 = 8000; %Hz
N1 = 1:90;
f2 = (N1)*f1;
V = zeros(size(3,N));

% for i = 1:3
for i = N1
    A =(1/N1(i))*sin(2*pi*f2(i)*t); 
    V(i,1:length(t)) = A(:);
end

% S = V(1,:) + V(2,:) + V(3,:);
S = sum(V, 1);
plot(S)
xlim([0 500])

Also, instead of

for i = 1:3

you can do

for i = N1
