function plotPhaseTile(xy, v, vPred)
%
%  plotPhaseTile(xy, v, vPred)
%
%  plots the phase and amplitude of eigenvector modes (or data) in xy space
%  using the complex eigenvector (or csm) v.  Uses scatter 3 since it does
%  not assume regular spacing.  v is assumed to be a  vector of complex
%  coefficients (solution is done as concatenated real then imaginary
%  coeffs, so you need to to assemble the complex valued list).  vPred is
%  the predicted eigenvector structure, for comparison

clf; colormap(hot);
va = angle(v)*180/pi;
vpa = angle(vPred)*180/pi;

scatter3(xy(:,1), xy(:,2), va, [], va, 'filled');
view(2); caxis([-180 180]); axis equal; colorbar; 
xlabel('x (m)'); ylabel('y (m)'); title('Observed phase')

scatter3(xy(:,1), xy(:,2), abs(v), [], abs(v), 'filled');
