Hi all, I have one set data below. Anyone know how to calculate the total area of particular coordinate?
let say I want to calculate the total area that have centroid (150 111) and (150 110) used this cide but have error
data = T;
T.Area = T(:,1);
T.Centroid = T(:,3:2);
Input1 =[150 111];
Input2 =[150 110];
output = sum(T.Area(((Input2(1)>=T.Centroid(:,1) & T.Centroid(:,1)>=Input1(1)))))
output2 = sum(T.Area(((Input2(1)>=T.Centroid(:,1) & T.Centroid(:,1)>=Input1(1))&(Input2(2)>=T.Centroid(:,2) & T.Centroid(:,2)>=Input1(2)))))
T =
1593×2 table
Area Centroid

data = T;
T.Area = data(:,1);
T.Centroid = data(:,[3 2]);
Input1 =[150 111];
Input2 =[150 110];
dis1 = T.Centroid-repmat([150 111],length(T),1);
dis1 = dis1(:,1).^2+dis1(:,2).^2;
dis2 = T.Centroid-repmat([150 110],length(T),1);
dis2 = dis2(:,1).^2+dis2(:,2).^2;
ind = dis1<=1 & dis<=1;
sum(T.Area(ind))

data = T;
save data.mat data
sir,can you run and save data.mat , then upload it to develop

Some minor error
T.Centroid = T(:,[3 2]);
Variable index exceeds table dimensions.
