I posted a few days ago about same question.

But I can't understand well and I think it is not accurate about "polyfitc" when I used it.

For example,

RNodes(2.8667)>>>Aero Twst(13.308), RNodes(2.8667)>>>chord(3.532)

I want to express such as upper.

it means that they are related mutually.

when I posted such as similiar question before, I got reommendation to use "polyfit"

But it was not accurate compared to original values when I graphed.

And I got another answer, but I coudln't understand well.

so Could you help me again ?

Fred already pointed you to "linterp" in his reply in the other thread you are referring to and I guess for your case linear interpolation will be good enough.

I am not sure but I guess that the Maxwell book you are reading has a chapter on interpolation, too - right?

So why are you still not going to study the basics of Prime? After all your math background should tell you that you need some sort of interpolation as I understand your post in that way that you are not happy with a regression/approximation.

MoreoverI think you should read a bit more about the Excel component and how to use it. You don't need that component at all if you use READEXCEL as you did in your sheet.

The attached sheet should help.
