.Wavelet.MRA.mra

Information

This function carries out the complete wavelet MRA and outputs decomposed signals in all levels after coefficient tuning. Please note that only the wavelets of types 1 (orthogonal), 2 (bi-orthogonal) and 3 (discrete Meyer) are possible for MRA. Otherwise running errors will occur.

Since default values are provided with this function, a direct execution of this function without extra input parameters will deliver a simple example.

Refer to the description of Families for detailed information about the available wavelets.
