toeplitz matrix

New to Julia

Hi

using ToeplitzMatrices
r=zeros(1,5)
r[1:2]=[2.0,-1.0]
Toeplitz(r,r)

ERROR: MethodError: no method matching Toeplitz(::Array{Float64,2}, ::Array{Float64,2})

However, in Matlab:

 r=zeros(1,5);
r(1:2)=[2,-1];
T=toeplitz(r);

T =

     2    -1     0     0     0
    -1     2    -1     0     0
     0    -1     2    -1     0
     0     0    -1     2    -1
     0     0     0    -1     2

how can we solve this bug in Julia?
