Category

Transformation

Function

Computes the gradient of a scalar field.

Syntax

gradient = Gradient(data, method);

Inputs

Name	Type	Default	Description
data	scalar field	none	field whose gradient is to be computed
method	string	"manhattan"	method to use

Outputs

Name	Type	Description
gradient	vector field	gradient field

Functional Details

data	is the scalar field.
method	specifies how the gradient will be computed. At present, the only method supported is "manhattan."

Components

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

Example Visual Programs
