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.
