function [scales,xtick,ytick] = CalcCWTScale(sz)
% CalcCWTScale -- Calculate Scales and TickMarks for CWT Display
%  Usage
%    [scales,xtick,ytick] = CalcCWTScale(sz);
%  Inputs
%    sz      size of CWT array
%  Outputs
%    scales  vector of scales in CWT
%    xtick   vector of positions
%    ytick   vector of log2(scales)
%  

	n = sz(1); nscale = sz(2);
	noctave = floor(log2(n))-5;
	nvoice  = nscale ./ noctave;
	scales  = 2.^(2 + (1:nscale)./nvoice);
	xtick   = (.5:(n-.5))./n;
	ytick   = (2 + (1:nscale)./nvoice);
