Thank you for mine in answer to a question

I intend to make the curved surface roof using this function

What should I input into VB?

1) Download the Meta.Numerics.dll from the "Content ZIP" from https://metanumerics.codeplex.com/releases/view/611568

2) Unblock dll file.

3) In GH, invoque a VB script component. Right click > manage assemblies > add Meta.Numerics.dll.

4) Set first param as "nu" and type hint double. Set second param as "x" and type hint double. Set First ouput as F and second output as S.

5) Double click over component and type:

Dim sp As meta.Numerics.Functions.SolutionPair = Meta.Numerics.Functions.AdvancedMath.Bessel(nu, x)
F = sp.FirstSolutionValue
S = sp.SecondSolutionValue

In this forum, the post cannot post files in comments, you should have opened a discussion instead.

I usually do not answer questions such as "seek information and make me my job," but to find this library, I wanted to see what was in it. So... what you want to try with this? What are you going to do? Please, surprise me a bit.
