In this paper, the concepts of Daubechies wavelet transform are discussed. The Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function which generates an orthogonal multi resolution analysis.

This disk contains numerical methods software coded in MATLAB. The algorithms are described in the text NUMERICAL METHODS for Mathematics, Science, and Engineering.FORTRAN
