probnum.linops

Finite-dimensional Linear Operators.

This package implements finite dimensional linear operators. It can be used to represent linear maps between finite-dimensional vector spaces without explicitly constructing their matrix representation in memory. This is particularly useful for sparse and structured matrices and often allows for the definition of a more efficient matrix-vector product. Linear operators support common algebraic operations, including matrix-vector products, addition, multiplication, and transposition.

Several algorithms in the probnum.linalg subpackage are able to operate on LinearOperator instances.

Functions
