lazymatrix::MatTransposeVecInto

LazyMatrix for Rust · 0.8.1

Source

pub trait MatTransposeVecInto<X, Y = X>: MatrixShape + MatrixErrorType

Transposed matrix–vector product out = Aᵀ x, overwriting reusable output storage.

X and Y may differ so that backends can accept borrowed or strided inputs while writing into an owned output. Implementations must not depend on the previous values in out.

Errors

Returns the backend error if the product cannot be completed. After an error, out may be partially overwritten and must not be used as a product result.

Panics

Panics unless x has length nrows and out has length ncols.

Methods

mat_transpose_vec_into

fn mat_transpose_vec_into(
    &self,
    x: &X,
    out: &mut Y
) -> Result<(), <Self as MatrixErrorType>::Error>

Source

mat_transpose_vec_normalized_into

fn mat_transpose_vec_normalized_into<F: lazymatrix::Scalar>(
    &self,
    x: &X,
    centers: Option<&[F]>,
    scales: Option<&[F]>,
    out: &mut Y
) -> Result<(), <Self as MatrixErrorType>::Error> where X: lazymatrix::SumEntries<F>, Y: lazymatrix::ScaledSubSlice<F> + lazymatrix::ElemDivAssign<F>

Source

Apply the transpose of the optionally normalized matrix.

Backends may center entries before accumulation to avoid cancellation.
