Hi everyone, I have three variable x, y and T. x and y are independent variables and T is dependent variable. I have the T as an output at particular points (e.g. at specified lines grids). Is there any function similar to interp1 in 2D data that can be used to find T at any point in the data contour?
Thank you, Aziz

interp2() if the points are along straight lines. Otherwise griddata() or triscatteredinterp()

the points are along straight lines but how I apply this data matrix to the function interp2()

interp2(YourXValues, YourYValues, YourDataMatrix, XPlacesYouWantToInterpolate, YPlacesYouWantToInterpolate)
