How to find corresponding value in Y vector for a non given value in X vector?

Suppose I have 2 vectors, A = [180 230 260 300 360] B = [1.2 3.2 5.6 7.9 9.1]

How do I find value of B for a value of A which is not given? For eg. A = 210.22, B = ?

Do interpolation....doc interp1..

Bi=interp1(A,B,210.22)

Hi, Thanks for your Answer. How I find for a value that is beyond the limits of the A vector? Such as 130?

It s very much given in the documentation.....I asked you to read the documentation.

Bi = interp1(A,B,130,'linear','extrap')

But note that...you should be careful with the extrapolation.
