I ran the code from docs homepage:

xs = 1:0.2:5
A = log.(xs)
interp_linear = extrapolate(scale(interpolate(A, BSpline(Linear())), xs)) # errors
itp = interpolate(A, BSpline(Linear())) # errors

As a side note, this made me wonder, because the following example does not fail:

scaled_itp = scale(interpolate(A, BSpline(Linear())), xs)

Although the first argument to scale is exactly itp from above which fails. Just for general knowledge, how is it possible that when I evaluate an expression it errors but when this expression is fed into another function it does not?
Thanks

You're right, extrapolate is missing a second argument.

It should be

interp_linear = extrapolate(scale(interpolate(A, BSpline(Linear())), xs), Throw())

Notice that the linked PR only addresses the first of the two errors.

That line seems to work for me. What error do you encounter?

Did you not do using Interpolations before hand?

For me, running

using Interpolations
xs = 1:0.2:5
A = log.(xs)
itp = interpolate(A, BSpline(Linear()))

returns

Some type information was truncated. Use `show(err)` to see complete types.

I'm running Interpolations v0.14.7 on Julia 1.10.0. I now see that this is not the newest version of Interpolations, but apparently I can't upgrade due to some compatibility constraint. Also I see now that running

itp = interpolate(A, BSpline(Linear()));

runs just fine, so indeed the problem is only with the displaying
