%blok c
c = mat2cell(Temp, [16 16 16 16 16 16 16 16 16 16 16 16] , ...
[16 16 16 16 16 16 16 16 16 16 16 16]);
%blok e
e = mat2cell(Y, [8 8 8 8 8 8 8 8] , [8 8 8 8 8 8 8 8]);
%scalling blok c --> d
for cc=1:12
for dd=1:12
d{cc,dd}=rata(c{cc,dd});
end
end
% block d and e process
for yy=1:12
for zz=1:12
for aa=1:8
for bb=1:8
min{yy,zz,aa,bb}=d{yy,zz}-e{aa,bb};
rms{yy,zz,aa,bb}=
(sqrt(sum(sum((min{yy,zz,aa,bb})^2))))/64;
mintemp(yy,zz,aa,bb)=rms{yy,zz,aa,bb};
end
end
end
end
% find the minimum value
out=min(mintemp(:));
this is my program, when i try your advice, there's error : ??? Subscript indices must either be real positive integers or logicals.
Error in ==> secret12 at 102 out=min(mintemp(:));

You have a variable named "min" somewhere in your workspace. MATLAB thinks you are referring to this variable rather than the MIN function. Rename the variable to something that isn't a MATLAB function name.

Try
clear min
out=min(mintemp(:));

v=mintemp(:,:,1,1);
out=min(v(:))

how about to find minimum value not only in mintemp (:,:,1,1) but also continue until (:,:,8,8) or the whole e. so, i get 64 minimum value.

Please, post correctly your question. Post a sample of your data, then ask clearly what you want.
