1d scattered data interpolation

Hey everybody,

Matlab is becoming my arch enemy and I need some brave soldier to help me with my next battle, I have the following data:

x=[23 312 6546] y=[3 43 342]

So I can make a scattered 'graph' of points (x,y)

Now I want to linearly interpolate for example in the point, say (6,*) how can I do this? I used already 'griddedInterpolant' and other options!

Thank you very much in advance,

James

6 is not within your range of x values, so you cannot interpolate to there; you would have to extrapolate.

Answer 1

[Walter Roberson]

interp1(x, y, 6)

Answer 2

Thanks Roberson I know I can do for example interp1(x,y,43)!

Much appreciated,

James
