Exporting Interpolation of 2D data in 2D format

Hello,

I have a 2D unstructured mesh data from numerical result. I would like to interpolate the data in matlab and export the interpolated data to be post process with gnuplot. My initial data attached herewith is in the form of x, y, U. But the interpolated data data is in form of mesh mxn.

How can I convert the interpolated data into the initial format of x,y,U?

I attached herewith the data;

data = importdata('2Ddata.txt');
x = data(:,1);
y = data(:,2); 
v = data(:,3); 

[xx,yy] = meshgrid(min(x):0.1:max(x),min(y):0.1:max(y));

 vq = griddata(x,y,v,xx,yy);

Thanks

Hello,

I found the solution to the problem

to recontruct the griddata into table, use

out = [xx(:) yy(:) zz(:) vq(:)];
