%  MakeCDJVFilter --  Set up filters for CDJV Wavelet Transform
%   Usage
%     [a,b,c] = MakeCDJVFilter(request,degree)
%   Inputs
%     request  string: 'HighPass', 'LowPass', 'Precondition', 'Postcondition'
%     degree   integer: 2,3,4,5,6,7 or 8 (number of vanishing moments)
%   Outputs
%     a,b,c    filter, left edge filter, right edge filter
%              ('HighPass', 'LowPass')
%     a        conditioning matrix ('PreCondition', 'PostCondition')
% 
%   Description
%     CDJV have developed an algorithm for wavelets on the interval which
%     preserves the orthogonality, vanishing moments, smoothness, and compact
%     support of Daubechies wavelets on the line.
% 
%     The algorithm for wavelets on the interval of CDJV involves four objects
%     not present in the usual periodized algorithm: right edge filters, left
%     edge filters, and pre- and post- conditioning operators.
% 
%     These objects are supplied by appropriate requests to MakeCDJVFilter.
