intbasis

  

determine a basis for the intersection of spaces

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

intbasis(S1, S2, ..., Sn)

Parameters

S[i]

-

vector, set of vectors, or list of vectors

Description

• 

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

  

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

• 

A basis for the intersection of the vector spaces spanned by the vectors in Si is returned.

• 

A basis for the zero-dimensional space is an empty set or list.

• 

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