Function: wavpack2cell

WAVPACK2CELL Changes wavelet coefficients storing format
  Usage:  
         ccell = wavpack2cell(cvec,Lc);
         ccell = wavpack2cell(cvec,Lc,dim);

  Input parameters:
        cvec     : Coefficients in packed format.
        Lc       : Vector containing coefficients lengths.
        dim      : Dimension along which the data were transformed. 

  Output parameters:
        ccell    : Coefficients stored in a cell-array. Each element is
                   a column vector or a matrix.
        dim      : Return used dim. Usefull as an input of the
                   complementary function WAVCELL2PACK.

  ccell = WAVPACK2CELL(cvec,Lc) copies coefficients from a single column
  vector or columns of a matrix cvec of size [sum(Lc), W] to the cell
  array ccell of length length(Lc). Size of j*-th element of ccell*
  is [Lc(j), W] and it is obtained by:

     ccell{j}=cvec(1+sum(Lc(1:j-1)):sum(Lc(1:j),:);

  ccell = WAVPACK2CELL(cvec,Lc,dim) allows specifying along which
  dimension the coefficients are stored in cvec. dim==1 (default)
  considers columns (as above) and dim==2 rows to be coefficients 
  belonging to separate channels. Other values are not supported. For 
  dim=2, cvec size is [W, sum(Lc)], Size of j*-th element of ccell*
  is [Lc(j), W] and it is obtained by:

     ccell{j}=cvec(:,1+sum(Lc(1:j-1)):sum(Lc(1:j)).';
