How to locate the centre of vector field (or a vortex field) using quiver plot.

If you download the "vortex_velocity_data.mat" file you will be able to create the vector field which I created.

Once the code is impoted to the workspace, I type the following code, to get the quiver plot:

quiver(x,y,ud,vd)

How would I locate the centre of this quiver/vecor plot WITHOUT using the 'Data Cursor' ?

What lines of code will I have to write in order to locate the centre?

By locating the centre x and y co-ordinates i can find the relative velocity componets (u,v)

Hi! I am facing the exact same issue. Could you eventually solve the problem or figure out how to do that? It would be a great help if you could share :)
