lazymatrix::MatTransposeVecScaledInto

LazyMatrix for Rust · 0.8.1

Source

pub trait MatTransposeVecScaledInto<X, Y, F>: MatrixShape + MatrixErrorType

Fused transpose product out = alpha * Aᵀ * x + beta * out.

Exact zero alpha skips the product, including any storage reads. Exact zero beta overwrites without reading prior output values. Dimensions are checked even when a coefficient is zero. On an operational error, out may be partial.

Panics

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

    alpha: F,
    x: &X,
    beta: F,
    out: &mut Y
) -> Result<(), <Self as MatrixErrorType>::Error>

try_mat_transpose_vec_scaled_normalized_into

fn try_mat_transpose_vec_scaled_normalized_into(
    &self,
    _alpha: F,
    _x: &X,
    _beta: F,
    _centers: Option<&[F]>,
    _scales: Option<&[F]>,
    _out: &mut Y
) -> Option<Result<(), <Self as MatrixErrorType>::Error>> where F: lazymatrix::Scalar, X: lazymatrix::VectorView<F>, Y: lazymatrix::VectorViewMut<F>

Source

Try a specialized fused normalized transpose product.

None leaves output untouched. Some obeys the fused product's dimension, zero-coefficient, and error contracts.
