divergence

Computes the divergence of a vector field

Syntax

Description

div = divergence(X,Y,Z,U,V,W) computes the divergence of a 3-D vector field U, V, W. The arrays X, Y, Z define the coordinates for U, V, W and must be monotonic and 3-D plaid (as if produced by meshgrid).

div = divergence(U,V,W) assumes X, Y, and Z are determined by the expression

where [m,n,p] = size(U).

div = divergence(X,Y,U,V) computes the divergence of a 2-D vector field U, V. The arrays X, Y define the coordinates for U, V and must be monotonic and 2-D plaid (as if produced by meshgrid).

div = divergence(U,V) assumes X and Y are determined by the expression

where [m,n] = size(U).

Examples

This example displays the divergence of vector volume data as slice planes using color to indicate divergence.
