checkchildren.m

EZW implementation which will use wavelet transforms and do the compression decompression using EZW

function   [RR]=checkchildren(j,RR)
set(0,'RecursionLimit',10000);
% if a symbol 't' is encounted, then make all its descendants in reference  
% matrix RR's components equal 1---ZEROTREES
global N
[m,n]=size(N);
for i=(4*j-3):4*j;
    if  i<=m, 
        RR(N(i,1),N(i,2))=1;
        [RR]=checkchildren(i,RR);
    end
end;
