Solving MATLAB Duplication Error with For Loop

[Superposed_Cat]

Hi, I'm totally new to MATLAB and tried this for loop

for K = 1:10
  disp(abs(tan(K)))
end

it displays

1.5574
 2.1850
 0.14255
 1.1578
 3.3805
 0.29101
 0.87145
 6.7997
 0.45232
 0.64836

Why did it display this twice?
Thanks for any help.

The shortest answer is that it only displayed it once for me when I ran the same code in R2012a.

Thanks, When I did it again it worked without changing anything but it happened again and duplicated a graph.

If you don't show me anything to go with, I can only assume you sneezed while hitting enter, or that you were drunk and seeing double.

lol, the button only allows you to press it once before changing to a animated non-clickable gear.

try "clc" before the script
