% MultiVisu2 -- Apply sqrt(2log(n)) Thresholding to Wavelet Coefficients
%  Usage
%    ws = MultiVisu2(wc,L)
%  Inputs 
%    wc    Wavelet Transform of noisy sequence with N(0,1) noise
%    L     low-frequency cutoff for Wavelet Transform
%  Outputs 
%    ws    result of applying VisuThresh to each High Frequency
%          Dyadic Block
