function I=gha_recompose(coeffs,W,mval)

% I=recompose(coeffs,W,mval)
%
% coeffs - decomposition coefficents as determined via gha_getcoeffs.m
%
% mval scales the final output in the following line
%    I=gha_unchopst(imdat*mval, r, c, 8, 8);
% so if you want things to remain as normal, set mval = 1
