How to derive the 2D field and convergence based on xy gradients
1 view (last 30 days)
This might be an easy question but I am a bit stuck on it. The function gradient yields xy gradients of a 2D field:
[px,py] = gradient(z);
But how do I move the other way? I.e.: z=f(px,py) where I have px and py and f is the unknown function/mechanism. My first thought revolves around using filter2 but I can't seem to figure it out.
Secondly: What would be an easy way to determine whether a region is subject to convergence/divergence?

For your first question:
For your second question:
I don't understand what you mean by: determine whether a region is subject to convergence/divergence ?
