Functions like rand(m,n) generate a random matrix of m rows and n columns. Is there any function in Julia that can generate a Symmetric matrix of arbitrary dimensions?

You can create a symmetric matrix as you do in rand(m,n), but you will not be able to assign to non-diagonal elements as that might break its symmetry. So, you should create the general matrix first then convert to symmetric.
Symmetric(rand(0:9,5,5))
5×5 Symmetric{Int64, Matrix{Int64}}:
5 2 1 4 1
2 1 6 8 0
1 6 2 0 6
4 8 0 7 1
1 0 6 1 4
