result = div(x, y, z [, order=order])

This function calculates the divergence of a 1, 2, or 3-dimensional vector function sampled on a uniform grid.

An array of the same shape as data, giving the divergence at each point.

x in required

The x component of the vector field.

y in required

The y component of the vector field. Optional

z in required

The z component of the vector field. Optional

order in optional

The order of the lagrange interpolation polynomial to use when calculating derivatives. See pdiv.pro for details. Defaults to 1.
