Copy-constructs a LinOp.
Inherits executor and size from the input.
|
inline |
Move-constructs a LinOp.
Inherits executor and size from the input, which will have size 0x0 and unchanged executor afterwards.
|
inline |
Performs the operation x = alpha * op(b) + beta * x.
alpha | scaling of the result of op(b) |
b | vector(s) on which the operator is applied |
beta | scaling of the input x |
x | output vector(s) |
References gko::ptr_param< T >::get(), gko::PolymorphicObject::get_executor(), gko::make_temporary_clone(), and gko::one().
Applies a linear operator to a vector (or a sequence of vectors).
Performs the operation x = op(b), where op is this linear operator.
b | the input vector(s) on which the operator is applied |
x | the output vector(s) where the result is stored |
References gko::ptr_param< T >::get(), gko::PolymorphicObject::get_executor(), gko::make_temporary_clone(), and gko::one().
Returns true if the linear operator uses the data given in x as an initial guess.
Returns false otherwise.
Returns the size of the operator.
Copy-assigns a LinOp.
Preserves the executor and copies the size.
Move-assigns a LinOp.
Preserves the executor and moves the size. The moved-from object has size 0x0 afterwards, but its executor is unchanged.
