MATLAB: There is a way that if clause it is execute

Question

Here it is a piece of code:

x = rand;
if x < 1E-6
   do-something
end

if I execute this piece of block in loop, the program never execute if clause because x is always bigger. how can I enter in that block?

Answer 1

Try this:

    for ii = 1 : 1e7
        x = rand;
        if x < 1E-6
           disp( 'do-something' )
        end
    end
    do-something
    do-something
    do-something
    do-something
    do-something
    do-something
    do-something

Thus, in this case it was executed seven times. (R2012a,64bit,Win7)
