so all it sees is a jumbled list of scattered points in space. The noise in that data means the data becomes folded upon itself in random ways. Now, let me look at T. Look carefully at the stuff in that region where all of your data is rolled up tight along the edge. ...
The nufftn( )function computes the NUDFT based on provided sample points and optionally, query points. Your goal is to convert your scattered samples into a structured grid, which requires careful setup of both the input data and the target grid. You have 100 random sample points (x, y) ...
then , if you really want to do meshgrid & interpolation, I noticed than 500 or 2500 points of interpolation, nor the method used had a great effect on reducing (to zero) the little "steps" close to the boundary; the only fix I could suggest here is to add a bit of 2D smoothing ...

Interpolates scattered data - generally to produce gridded data Vq = griddata(X,Y,V,Xq,Yq) fits a surface of the form V = F(X,Y) to the scattered data in (X, Y, V). The coordinates of the data points are defined by the vectors (X,Y) and V defines the corresponding values. ...

I use the text command in the example above, but is there a better way that you are pointing me to? Like an input argument that I should use?
