You are trying to plot the value 0 (the first element in `w_wn`) on a logarithmic scale, which is impossible since it would have to be drawn at negative infinity. You get the same error message from

```julia
plot( [0], [1], xscale=:log10 )

```

Also, you probably don’t need to call `collect` on your range.  
If you want to initialize `beta1` as the same size as `w_wn` in order to fill it in a loop you can use `similar(w_wn)`, or `zeros(size(w_wn)...)`. But you can also initialize `beta1` directly with a broadcasting computation on `w_wn` instead of that loop.
