Hey Rayhan,
You can try with these lines of code:
a = -5;
b = 5;
N = 100;
r = a + (b-a).*rand(N,1);
Hope it helps!

Ran in:
Most likely, if you receive the error given in the original question, you've defined a variable named rand that prevents MATLAB from calling the rand function. To check, what does this show?
which rand
built-in (/MATLAB/toolbox/matlab/randfun/rand)
If you have a variable with that name, you'd see this instead:
rand = 42;
which rand
rand is a variable.
Clear the variable and modify your code (if necessary) to avoid creating a variable of that name.
