How can I generate random numbers

Let a1=[3.698247068550237,7.396494137100475]

Let a2=[-0.315547526817319,-0.105392873956985]

Hw to find the random numbers in the following code

arr(i).Position=unifrnd(a2,a1,10);

The above is not working

What are you trying to do? You want 10 values, but you only specify 2 ranges.

I want a2 should generate one randon no, a1 should generate one random no and then a new range should form and i should be able to get 10 nos between that range.

So you want some sort of recursive behavior? That is not what that function does, so if you want it, you will have to write it.

It is still not quite clear to me what you want, so I can't help you write it.

i want a random no from a1

let

a1=4 (generated by random function)

a2=-0.2 (generated by random function)

then

arr(i).Position=unifrnd(-0.2,4,10);

"I want a2 should generate one randon no, a1 should generate one random no and then a new range should form and i should be able to get 10 nos between that range"

a1=[3.698247068550237,7.396494137100475];
a2=[-0.315547526817319,-0.105392873956985];
a1_rand=a1(1)+(a1(2)-a1(1))*rand(1)
a2_rand=a2(1)+(a2(2)-a2(1))*rand(1)
val_data=a1_rand+(a2_rand-a1_rand)*rand(10,1)

Result:

a1_rand =
    5.0835
a2_rand =
   -0.1176
val_data =
    4.5689
    4.9690
    4.0361
    1.1713
    0.6007
    2.5884
    4.7619
    1.3051
    4.1624
    1.0135
