Silly question, I guess… So: `linspace()` has been replaced by `range()`. But what about `logspace()`?

I tried to do it manually as, e.g., `10.^(range(-2,stop=2,length=50))`, but that doesn’t work.

- Is there a built-in new function for `logspace()`, or
- What is the way to use dot-notation and raise a scalar to an array?

I can do it as:

```nohighlight
v = range(-2,stop=2,length=50)
[10^i for i in v]

```

but that seems kind of clumsy??

In Julia 0.7,

```julia
logspace(1,10)
Warning: `logspace(start, stop)` is deprecated, use `exp10.(range(start, stop=stop, length=50))` instead.

```

What you wrote is fine, too, you just need a space between the `10` and the `.^` since otherwise it’s ambiguous if you mean `10. ^ x` or `10 .^ x`.
