Hello,
I have a set of data (x,y,v) that i got from CFD analesys.
x and y vector not unique or sort in any way, but there are not single (x,y) that repet.
i want to interpolate my data to get lower resolution but i cant get it to work
F = scatteredInterpolant(x_c,y_c,z_c);xi=linspace(min(min(x_c)),max(max(x_c)),100);yi=linspace(min(min(y_c)),max(max(y_c)),100);zi=F(xi,yi);[XI, YI] = meshgrid(sort(xi), sort(xi));ZI = griddata(xi, yi, zi, XI, YI);
ZI just return NAN
