Function fdata_interpolate 

Source 
pub fn fdata_interpolate(
    data: &FdMatrix,
    argvals: &[f64],
    new_argvals: &[f64],
    method: InterpolationMethod,
) -> FdMatrix
Expand description

Interpolate functional data to a new grid.

Resamples each curve from data evaluated at argvals to the new evaluation points new_argvals.

§Arguments

  • data - Functional data matrix (n x m)
  • argvals - Original evaluation points (length m, must be sorted)
  • new_argvals - New evaluation points (length m_new, must be sorted, within original domain)
  • method - Interpolation method

§Returns

Interpolated matrix (n x m_new)
