Frequency band for DWT

with this code you can find approximation frequency band cA and detail frequency bands cD of a DW.

Description

Here :
                    % "fs" is the sample frequency
                    % "lv" is level of decomposition
            % Output are :
                    % "cA" is approximation frequency band
                    % "cDlv" is matrix of "lv" detail frequency bands.
