How to plot with continuous line

Hi, I have an array and I want to plot it into graph. My problem is I got a dotted graph line and not a continuous one. How should I change my code to solve this problem? My code look like this:

Figure(1) hold on

for i= 1:5 array(i) = i*3; plot (i, array(i)); end

Use plot after the loop

 for ii= 1:5
    x(ii)=ii 
    array(ii) = ii*3; 
  end
 plot (x, array);

%don't use i and j as variables (used with comlex numbers)

Thank you very much for your reply. Can I know why I need to use the complex number?

[Azzi Abdelmalek]

No, I did say don't use i or j as variables in your code, just choose other variables, k,l,m,n,... Because ii*3 can be confused with the complex number ii*3

Ooo..now I understand..Thank you

One more question. Do you know what is the maximum elements of array that Matlab can support?

[Azzi Abdelmalek]

I can't tell exactly, that depends on your matlab version, also on your computer power and memory. look at this link http://www.mathworks.com/support/solutions/en/data/1-IHYHFZ/index.html
