Function memd 

pub fn memd(channels: &[Signal<f64>], config: &MEMDConfig) -> Result<MEMDResult>

Perform Multivariate Empirical Mode Decomposition.

All channels must share the same length. Use ≥ 2 channels; for a single channel call super::emd::emd instead.

Errors

• WaveletError::InvalidParameter if channels is empty or has 1 element, or if any config field violates its precondition.
• WaveletError::InvalidLength if channel lengths disagree.
• WaveletError::NumericError if any sample is non-finite, or if the cubic-spline interpolator hits a singular system.
