there is a 3d set of data... i want to find the equation that interpolates it... i m a beginner to MATLAB... i tried a few things that are not working.. i have no idea how to find such equation,,, kindly help me out...

data is as follows:

range 200 300 400 500 600 700 800... horizontal angle 15.8 20.2 25.6 31.4 37.4 43.8 50.... vertical angle -25 -25 -25 -25 -25 -25 -25....

i made a matrix of the currrent data and interpolated the data via interp2....but now i need to find an equation that can satisfy this data... n i m unable to do that...

i m using matlab 7.6.0

There are an infinite number of equations that interpolate it. Which one do you want?

在 MATLAB Online 中打开

Look up the command

interp3

interp3() does not create an equation.
