WebAug 17, 2010 · Green's theorem in matlab? hey guys I posted a message a couple of weeks ago about calculating the area inside a closed curve, well, some guys gave me this formula: area = 1/2*abs (sum (X.*Y ( [2:end,1])-Y.*X ( [2:end,1]))); and it works perfectly, so thanks very much whoever did, sorry I don't remember their name now, I think it's Roger. WebFortunately, George Green demonstrated the following theorem in 1828: Green's Theorem.

WebHere is a clever use of Green's Theorem: We know that areas can be computed using double integrals, namely, ∫∫ D1dA computes the area of region D. If we can find P and Q so that ∂Q / ∂x − ∂P / ∂y = 1, then the area is also ∫∂DPdx + Qdy. It is quite easy to do this: P = 0, Q = x works, as do P = − y, Q = 0 and P = − y / 2, Q = x / 2. highlights french open 2022WebFeb 4, 2014 · Green's Function Solution in Matlab.
