Greens theorem matlab code
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. WebMar 24, 2024 · Green's theorem is a vector identity which is equivalent to the curl theorem in the plane. Over a region in the plane with boundary , Green's theorem states (1) where the left side is a line integral and the right side is a surface integral. This can also be written compactly in vector form as (2)

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. ph range meaning
