I tried to find out the triangle area in the polygon based on determinant theory.
Here is the reference
I tried to calculate the area of triangles using indeces: function and for-loop.
function area = trianglearea(a)for i = 2 : length(i)-1; tri = [a(1,1), a(1,i), a(1,i+1); a(2,1), a(2,i), a(2,i+1); 1, 1, 1]; area = 0.5*det(tri)endend
A = [0 10 12 8 6 0; 0 1 4 6 8 0];trianglearea(A)
then the results is
and workplace is the results of area of triangles do not show each reasults following different i value in for-loop. It just show the final result when i = lengh(a)-1.
How can I display every triangle area..?
