mrpro.operators.MultiIdentityOp

class mrpro.operators.MultiIdentityOp[source]

Bases: EndomorphOperator

The Identity Operator.

An endomorph Operator that returns multiple inputs unchanged.

property H: Self[source]

Adjoint Identity.

__call__(*x: Tensor) → tuple[Tensor, ...][source]

Apply the EndomorphOperator.

adjoint(*x: Tensor) → tuple[Tensor, ...][source]

Adjoint Identity.

Parameters:

x (Tensor) – input tensor

Returns:

the input tensor

forward(*x: Tensor) → tuple[Tensor, ...][source]

Identity of input.

Parameters:

x (Tensor) – input tensor

Returns:

the input tensor

__add__(other: Operator[Unpack, Tout]) → Operator[Unpack, Tout][source]

__add__(other: Tensor) → Operator[Unpack, tuple[Unpack]]

Operator addition.

Returns lambda x: self(x) + other(x) if other is a operator, lambda x: self(x) + other*x if other is a tensor

__matmul__(other: EndomorphOperator) → EndomorphOperator[source]

__matmul__(other: Operator[Unpack, Tout]) → Operator[Unpack, Tout]

Operator composition.

__mul__(other: Tensor | complex) → Operator[Unpack, Tout][source]

Operator multiplication with tensor.

Returns lambda x: self(x*other)

__radd__(other: Tensor) → Operator[Unpack, tuple[Unpack]][source]

Operator right addition.

Returns lambda x: other*x + self(x)

__rmatmul__(other: Operator[Unpack, Tout]) → Operator[Unpack, Tout][source]

Operator composition.

__rmul__(other: Tensor | complex) → Operator[Unpack, Tout][source]

Operator multiplication with tensor.

Returns lambda x: other*self(x)
