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.
