How to plot coast and fill the land with gray without m_map

Dear all，

I have detailed shoreline data. I want to fill the land after ploting the coast. But I don't want to use m_map.

Thank

To fill the land use patch/ area/ fill. Read about those functions. To simply plot the coastline use plot.

load m_coasts.mat ;
% Get nan's
idx = all(isnan(ncst),2);
idr = diff(find([1;diff(idx);1]));
D = mat2cell(ncst,idr(:),size(ncst,2));

figure
hold on
for i = 1:length(D)
  patch(D{i}(:,1),D{i}(:,2),'b')
  plot(D{i}(:,1),D{i}(:,2),'k')
  drawnow
end
