linalg(deprecated)

  

kernel

  

compute a basis for the null space

  

nullspace

  

a synonym for kernel

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

kernel(A)

kernel(A, 'nulldim')

nullspace(A)

nullspace(A, 'nulldim')

Parameters

A

-

matrix

'nulldim'

-

(optional) unevaluated name

Description

• 

Important: The linalg package has been deprecated. Use the superseding command LinearAlgebra[NullSpace], instead.

  

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

• 

The procedure kernel computes a basis for the null space (kernel) of the linear transformation defined by the matrix A. The result is a set of vectors, possibly empty.

• 

When given an optional second parameter, kernel(A, 'nulldim'), in addition to the above, assigns the variable nulldim the vector space dimension of the kernel (a non-negative integer).

• 

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

Examples
