I grid my data using the following simple procedure:
Latitude=data1(:,8);
Longitude=data1(:,9);
latedges=-0.7:0.1:0.3;
lonedges=99.8:0.1:100.8;
for i=1:numel(lonedges)-1,
for j=1:1:numel(latedges)-1,
T(i,j)=size(data1(Longitude>=lonedges(i) & Longitude<=lonedges(i+1) & Latitude>=latedges(j) & Latitude<=latedges(j+1),:),1);
end;
end
It works but it is very slow. Is there another option to do it?
Thank you for help.
Edward
