how to increment variable while logical true?

Hi,

I am new to matlab, I want to increment a number when its true.

i tried doing this as a script

global variable;
variable = true;
while (variable)
   a=1;
   a=a+1;
   dips(a);
end

shouldn't this display an incremented value

1
2
3
4
.
.
.

but all i get is

2
2
2
2
.
.

Am i doing something wrong? help!

You're setting a back equal to 1 inside the loop. Why? That should be outside the loop. I think you should look at this: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

global variable;
variable = true;
a = 1;
while variable
   a=a+1
   if a > 20
      variable = false; % Break out of loop.
   end
end
