Suppose we take the red point on the polar grid. When i convert it to Re & Im parts i get a number in rectangular grid, but this point is not actually present in the rectangular grid shown on right. This polar point was found by interpolating some points. How can i find a point in rectangulr grid then?
It is not clear to me what you mean by "How can i find a point in rectangulr grid then?". What is "find" in this context?
I am having a 2D array , say Array 1, which is in the polar grid. I found this Array1 from another 2D array, ("Array2") by interpolation. Now I take some values from Array2 and need to find the corresponding values in the Array1. This is what i what.
I short i need to find the points in Array1 which i interpolated using the point i got by interpolation (Array2)
