3.1.1.2 MatrixFunction Objects

class MatrixFunction
MatrixFunction( matrix, domain, codomain, [name=])

Instances of class MatrixFunction have the following methods (in addition to inherited methods and special methods):

restrict_domain

These methods are defined as follows:

restrict_domain( sub)
Restrict this matrix function to a subspace sub of the domain. The subspace sub should have a basis() method and elements of the basis should be coercible into domain.

Instances of class MatrixFunction also have the following special methods:

__mul__( right)

The multiplication * operator is function composition for linear functions.

WARNING: Composition agrees with matrix multiplication, so f*g means "do f, then g", since matrices act from the right in SAGE.
