MATLAB: Best way to enter only one time in a if block

if statement

I have a for cycle
for n= 1: 100
  x=rand()*10;
  if x > 5
    do something
  end
end
When I execute this cycle it happens that if x is major than 5, the program enter in if clause. I would create a way that enter in if clause only one time even if the condition is true.which could be the best way?In Java I'd created this using boolean but matlab doesn't have boolean type

Best Answer

 test=0
 for n= 1: 100
    x=rand()*10;
    if x > 5 & test==0
       %do something
       test=1
    end
 end
