Rewriting a loop construct

Just a thought guys, how would you rewrite this loop construct?

     if i < 4
          subplot(4,1,i+1);
          plot(x,y); 
          title('Original');
      end

I did try to write it as follows but something went wrong outside the loop:

          subplot(4,1,i+1);
          plot(x,y); 
          title('Original');
          if i==2
          break
          end

What do you think of other loop constructs?

where is the loop? I mean what you're trying to do?

there's this if loop which I'm wondering if there could be an alternative for it. I'll write the code again which is my main subject of concern:

     if i < 4
          subplot(4,1,i+1);
          plot(x,y); 
          title('Original');
      end

That is not a loop. "if" does not cause looping: the body of the "if" is done once if the condition is true. Using a loop requires "for" or "while"

[Ayesha]

So could if be replaced by any other construct?

[Walter Roberson]

What kind of alternative were you hoping for? It's just an "if" statement with a simple body.

if you want to plot for i=1 to i=4,

for i=1:4

 subplot(4,1,i+1);
 plot(x,y); 
 title('Original');

 end

To be consistent, the upper end of the loop should be 3 rather than 4. The lower end could be adjusted to 0 instead of 1.
