rand gives you number(s) between 0 and 1, so with appropriate scaling and offsetting, you can use it to get number(s) from any given range:

data = 0.3 + 0.1*rand(1,100) % 100 numbers between 0.3 and 0.4

data = 1×100

0.3596 0.3187 0.3503 0.3990 0.3179 0.3482 0.3384 0.3025 0.3906 0.3738 0.3543 0.3069 0.3705 0.3117 0.3616 0.3272 0.3565 0.3828 0.3806 0.3173 0.3632 0.3188 0.3767 0.3447 0.3255 0.3521 0.3875 0.3934 0.3428 0.3297
