I am looking to generate random numbers between a certain set of decimal numbers (for eg: 0.3 to 0.4). I tried using rand command but if anyone has a workaround?

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
