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?

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)
