18.12.6 Multi-Scale Wavelet Decomposition

This function performs multi-level discrete wavelet decomposition. The input signal is first decomposed into approximation coefficients and detail coefficients. Then, depending on the decomposition level you have specified, the detail coefficients are decomposed into approximation coefficients and detail coefficients. The decomposition repeats n times, where n is the number of decomposition levels.
