Great and fast little tool. Much faster than matlab inpolygon. My only issue is that I wish it natively understood the typical "GIS" format for polygons which includes a NaN separated list of polygons (NaNs separate the major outline from the 'islands').
Of course you can just handle this with the edges field though, so for future reference, here's my simple create edges code for NaN separated GIS objects. 'shp' variable is n Nx2 matrix of latitudes and longitudes.
shpEnd = find(isnan(shp(:,1)));
shpEnd = vertcat(0,shpEnd);
edges = nan(length(shp(:,1))-length(shpEnd),2);
count = 1;
for j=1:length(shpEnd)-1
endCount = count+length((shpEnd(j)+1:shpEnd(j+1)-2));
edges(count:endCount,:) = [(shpEnd(j)+1:shpEnd(j+1)-2)' ...
(shpEnd(j)+2:shpEnd(j+1)-1)';shpEnd(j+1)-1 shpEnd(j)+1];
count = endCount+1;
end
