How to generate a costant signal?

I have some difficulties on this code. I want to generate a 10 V constant signal, which function should I use? In this short passage I generate a sinusoidal signal, thanks for support

N= 500; %number of samples
Np= 3; %number of periods

%% Sampling
n=(0:N-1)'; %indices of samples
Fx= Np/N; %digital frequency
wt= 2*pi*Fx*n; %argument of periodic functions

%% Sinusoidal signal, mean 0
Vmax=10; %max value
x_sin = Vmax*sin(wt);

figure(1)
plot(n*Fx,x_sin)

Here's an example that you can add to the bottom of your code

%% Constant signal
sigVal=3; % example value
x_const = sigVal*ones(N,1)
figure(2)
plot(n*Fx,x_sin,n*Fx,x_const)
