Interpolation Values from a Surface map
显示 更早的评论
Hello,
I have a calibration field from which i want to extract interpolated points.
I want to know what would be the Z value provided example X=200.35 and Y=78.89. And it would be ideal if i can extract multiple values like
Z=[Z1,Z2,Z3...Z10] which corresponds to values from
X=[X1,X2,X3....X10]
Y=[y1,y2,...Y10]
I have having a big problem doing this.
Any assistance would be really appreciable.
Viele Grüße,
Trfan Tahir

HI Irfan,
The interp2 function will solve this. See the following documentation. The function can be written as:
Zq = interp2(X,Y,Z,Xq,Yq)
so given that you have all your X,Y,Z data you just plug in your query points Xq and Yq which can be column vectors consisting of multiple query point. The output is your corresponding interpolated heights, Zq, corresponding to Xq and Yq.

Hi Irfan, I'm interested in the same thing. Did you figure out how to calculate Y if Xq and Zq are known?
