Editing Line Type Settings for data in a for loop

I am plotting an array that enters a for loop 4 times and therefore produces 4 different arrays and 4 different curves. When plotting like this, how do I differentiate line type settings for different curves plotted by one plot command?

Can you share your code?

[mht6]

N = [20 13 56 72]; 
for i = 1:length(N)
% Create A matrix then.. 

f = ones(N(i),1); 

h = 1/(N(i) + 1);
A_h = -A./(h.^2); 
u = A_h\f; 

x = linspace(0,1,N(i)); 
plot(x,u)

Do something like following:

N = [20 13 56 72]; 
line={'--','b--o','->','-*'};
for i = 1:length(N)
% Create A matrix then.. 
f = ones(N(i),1); 
h = 1/(N(i) + 1);
A_h = -A./(h.^2); 
u = A_h\f; 
x = linspace(0,1,N(i)); 
plot(x,u,line{i});hold on;
end
