Struct RandomizedConfig 

pub struct RandomizedConfig {
    pub rank: usize,
    pub oversamples: usize,
    pub sketch: Sketch,
    pub normalizer: Normalizer,
    pub mean_center: bool,
    pub seed: Option<u64>,
}

Configuration for svd_with.

Replaces 1.x’s eight positional arguments, two of which were bare bools that the crate’s own call sites commented incorrectly.

Fields

rank: usize

Number of singular triplets wanted.

oversamples: usize

Extra sketch columns; improves accuracy at linear cost.

sketch: Sketch

normalizer: Normalizer

mean_center: bool

Subtract column means without materialising the centered matrix.

seed: Option<u64>

Fixed seed; None draws from the OS.

1.x accepted Option<u64> but substituted 0 for None, so “random” was in fact a fixed sketch on every call.
