Calling Sequence

indexfunc(A)

Parameters

A

-

array

Description

• 

Important: The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.

  

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

• 

The procedure call indexfunc(A) returns the indexing function for the array A.

• 

This could be one of the standard indexing functions such as identity, symmetric, or diagonal, or the name of a user-defined indexing function.

• 

If there is no indexing function specified for the array A, then indexfunc will return NULL.

• 

The command with(linalg,indexfunc) allows the use of the abbreviated form of this command.
