I have a field which, when I plot, results in NaN values in between the known values. I want to interpolate the values on these NaN locations in the (blue) region only and keep rest of the region as NaN. I could not figure how exactly to achieve it.
Attached is .mat file of the field and following is the code to get the same plot.
ax = pcolor((v)); colormap(parula(50));
axis tight equal;colorbar
ax.LineStyle = 'none';ax.EdgeColor = 'flat';ax.FaceColor = 'flat';
ax.FaceAlpha = 1;
axis ij on equal
