find the minimum value

i have a matrix A with double class type data. i have to find the minimum value of matrix, the problem is the min function on matlab require integer data. is there matlab function to find minimum value on double class type data or function conversion between double to integer so min function can use ?

A=magic(5)  % Example
out=min(A(:))

% No, min function don't allow just inetger

%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(:));

how to find minimum value only in mintemp(:,:,1,1) ?

[Azzi Abdelmalek]

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

[Internazionale]

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.
