Source 
pub fn add_error_pointwise(
    data: &FdMatrix,
    sd: f64,
    seed: Option<u64>,
) -> FdMatrix
Expand description

Add pointwise Gaussian noise to functional data.

Adds independent N(0, σ²) noise to each point.

§Arguments

  • data - Data FdMatrix (n × m)
  • sd - Standard deviation of noise
  • seed - Optional random seed

§Returns

Noisy data FdMatrix (n × m)
