Wavelet Matrix
A Matrix composed of Haar Functions which is used in the Wavelet Transform. The fourth-order wavelet matrix is given by

A wavelet matrix can be computed in
steps, compared to 
for the FourierMatrix, where 
is the base-2 Logarithm.See also Fourier Matrix, Wavelet, Wavelet Transform- Helmholtz Differential Equation--Confocal Paraboloidal Coordinates
