Function decompose_matrix 

pub fn decompose_matrix(
    data: &FdMatrix,
    family: WaveletFamily,
    mode: BoundaryMode,
    level: Option<usize>,
) -> Result<Vec<WaveletCoeffs>, FdarError>

Multi-level orthogonal DWT over every row (curve) of an [FdMatrix].

Each row is a signal of length data.ncols(); the result holds one WaveletCoeffs per row, in row order. The batch path is exactly the per-row decompose applied to each row (data.row(i)), so its output is identical to calling decompose on each row individually.

Errors

• FdarError::InvalidDimension if the matrix has zero rows or zero columns.
• FdarError::InvalidParameter if the family is unsupported or an explicit level is invalid for the row length (surfaced from decompose).
