J=rand(9);
K=rand(12);
L=rand(10);
a=meshgrid(J,K,L);
sc=3;
[n,m,p0]=size(a);
SI=zeros(n,m,p0);
for ii=1:n
for jj=1:m
td(:,1)=reshape(a(ii,jj,:),p0,1);
if length(td(td>=0))/length(td)~=1
SI(ii,jj,:)=nan;
else
SI(ii,jj,1:sc-1)=nan;
A1=[];
for i=1:sc,
A1=[A1,td(i:length(td)-sc+i)];
end
Y=sum(A1,2);
nn=length(Y);
SI1=zeros(nn,1);
for k=1:12
d=Y(k:12:nn);
 Xn=Y(d);
    [zeroa]=find(Xn==0);
    Xn_nozero=Xn;Xn_nozero(zeroa)=[];
    q=length(zeroa)/length(Xn);
    parm=gamfit(Xn_nozero);
    Gam_xs=q+(1-q)*gamcdf(Xn,parm(1),parm(2));
    Z(d)=norminv(Gam_xs);
    end
SI1(:,1)=norminv(SI1(:,1));
    %output
            SI(ii,jj,sc:end)=SI1;
