Transform a set of "if" arguments into a unified "for" function

Hello kind people,

I'm trying to optimize this segment of a function. Currently, it will give an output to the user when n_dice =< than 3.

if(n_dice==1)
		Z= randi(6,1,n_trials);
end

if(n_dice==2)
		Z= randi(6,1,n_trials) + randi(6,1,n_trials);				
end

if(n_dice==3)
		Z= randi(6,1,n_trials) + randi(6,1,n_trials) + randi(6,1,n_trials);
end

I'm trying to chage it so that it will accept any number of n_dice, maybe by using a for...? I've tried stuff like

sdice = randi(6,1,n_trials);
for i = 1:n_dice
    X = sdice(i);
end
Z = sum(X)

Could you please suggest something?

if n_dice==1
    Z=randi(6,1,n_trials);
else
    Z=sum(randi(6,n_dice,n_trials));
end

Awesome man! Thanks!

n_trials=??  % define n_trials
n_dice=randi(6,1,n_trials);
Z=n_dice*randi(6,1,n_trials);
