r(r<0.5)=0

[Ata Ul]

is there a way to do this using find?

[Azzi Abdelmalek]

If you want, but it's unnecessary

r=rand(2,8)
idx=find(r<0.5)
r(idx)=0

IF you need you could find even more particular values using logical AND & (here && since scalar) or logical OR |

r(0.3<r && r<0.5) = 59
r(0.2>r || r>0.99) = 13

such as the above. Good Luck.
