DivCurl

Category

Transformation

Function

Computes the divergence and curl of a vector field.

Syntax


div, curl = DivCurl(data, method);

Inputs
Name Type Default Description
data vector field none field whose divergence and curl are to be computed.
method string "manhattan" method to use

Outputs
Name Type Description
div scalar field divergence field
curl vector field curl field

Functional Details

data

is the vector field to be operated on. The "data" component of the output fields (div and curl) contains the divergence and curl respectively. The other components of the original field remain unchanged in the output fields.

method

specifies the algorithm used to make the computation. Currently, the only method supported is "manhattan."

Components

Modifies the "data" component for the outputs. All other input components are propagated to the outputs.
