22.04.2012 · I would like to compute the circulation of a velocity field. I think that the best way would be to compute the vorticity and then calculate the surface integral. At the moment I have computed vorticity using curl(X,Y,U,V) Where X,Y,U,V are all 2D matrices. Now that I have vorticity, how can I calculate the surface integral of vorticity?

Integration Method Description 'auto' For most cases, integral2 uses the 'tiled' method. It uses the 'iterated' method when any of the integration limits are infinite. This is the default method. 'tiled' integral2 transforms the region of integration to a rectangular shape and subdivides it into smaller rectangular regions as needed. The integration limits must be finite.

Save this matrix, and then you can make it a continuous function using interp2: function z_interp = fun (x,y) z_interp = interp2 (Xdata,Ydata,Zdata,x,y); end. Then you can use integral2 to find the integral: q = integral2 (@fun,xmin,xmax,ymin,ymax) where @fun is your function handle that takes in two inputs. Share. Improve this answer.
