I have a cell which contains coordinates of different polygon,
eg: if 'A' is a cell which have coordinates of 26 polygon, so its size is 1x26.
Now i want to obtain the area of each individual polygon in the cell. How i can get that? I dont want the sum of area of all polygons, but want the area of individual polygons.

for i1=1:26
data =mycoordinates{i1}%coordinate of i1th polygon
data(end+1,:) =data(1,:)
for i=1:max(size(data))-1
s(i)=data(i,1) *data(i+1,2)-data(i,2)*data(i+1,1)
end
area(i1) = abs(sum(s)/2)
end
