MATLAB: What does ‘…’ mean in MATLAB

...scrpit

I came across this script and I've seen h = … what does it mean?
axis(1.2*[-1 1 -1 1])
axis square
box on
hold on
x = 0;
y = 1;
h = ...
n = 2*pi/h;
plot(x,y,.)
for k = 1:n
x = x + h*y;
y = y - h*x;
plot(x,y,.)

The three dots '...' tell matlab that the code on a given line continues on the next line.
It is used so that command lines don't stretch out too long to print or read easily.
ex.
set(1,'Position',[0,0,1,1],'Tag','MyTag','Color', ...
[.94,.94,.94]);
This code is interpreted as a single set command with multiple parameters.
In the script you posted, the line in question would actually be interpreted like this:
h = n = 2*pi/h;
which should cause an error.
Whoever wrote the script must be using it as a place holder for something else.
