# Using a for loop to print function values

I am trying to make a function that inputs Vs and outputs 0 if Vs<=0.6, and outputs VL-0.6 if Vs>0.6. I need this function to loop for a series of input Vs vector of values, and output a vector of values based on the function. The code I wrote currently keeps overriding the VL value and outputs only one scalar value. How do I make it output a vector of values?
V=0:Vs
for k = 1:length(V);
if Vs(k)<=0.6; %if this is true
VL(k)=0;% it prints a 0
else
VL(k)=Vs-0.6; % prints a Vs-0.6 value.
end
end

Seems you are confusing Vs with V. And what is VL-0.6 in your question? Try this... (outputs a vector of values)
V = rand(1,10); % test data --> your inputed Vs
for k = 1:length(V)
if V(k) <= 0.6 % if this is true
VL(k) = 0; % it prints a 0
else
VL(k) = V(k) - 0.6; % prints a V-0.6 value
end
end
VL
Actually, it is not clear what you are trying to do, but the code above outputs a vector for VL -- your main objective, if I understand correctly.
