Function add_error_curve 

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

Add curve-level Gaussian noise to functional data.

Adds a constant noise term per curve: each observation in curve i has the same noise value.

§Arguments

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

§Returns

Noisy data FdMatrix (n × m)
