Trait collenchyma_blas::plugin::Axpy [−] [src]

pub trait Axpy<F> {
    fn axpy(&self, a: &mut SharedTensor<F>, x: &mut SharedTensor<F>, y: &mut SharedTensor<F>) -> Result<(), Error>;
    fn axpy_plain(&self, a: &SharedTensor<F>, x: &SharedTensor<F>, y: &mut SharedTensor<F>) -> Result<(), Error>;
}

Provides the axpy operation.

Required Methods

fn axpy(&self, a: &mut SharedTensor<F>, x: &mut SharedTensor<F>, y: &mut SharedTensor<F>) -> Result<(), Error>

Computes a vector x times a constant a plus a vector y aka. a * x + y with complete memory management.

Saves the resulting vector back into y. This is a Level 1 BLAS operation.

For a no-memory managed version see axpy_plain.

fn axpy_plain(&self, a: &SharedTensor<F>, x: &SharedTensor<F>, y: &mut SharedTensor<F>) -> Result<(), Error>

Computes a vector x times a constant a plus a vector y aka. a * x + y without any memory management.

Saves the resulting vector back into y. This is a Level 1 BLAS operation.

Attention:
For a correct computation result, you need to manage the memory allocation and synchronization yourself.
For a memory managed version see axpy.
