MATLAB: Error in script Subscript indices must either be real positive integers or logicals.

indices

I am trying to calculate the mean, max and min values from an array under some condition and at some specific case i get a very "strange" error
Subscript indices must either be real positive integers or logicals.
Error in MeanHourlyTOC (line 31)
                minTOC = min(dummy);
since i am able to calculate the max and mean values and this error is referred just in the min value. My code is as follow
l=0;
for i=1982:2012
    for j=1:12
        for k=1:24
              idx=find(Yr==i&M==j&T==k);
              dummy=TOC(idx);
              dummy(isnan(dummy))=[];
              if ~isempty(dummy)
                  l=l+1;
                  mTOC = mean(dummy);
                  sTOC = std(dummy);
                  maxTOC = max(dummy);
                  minTOC = min(dummy);
                  dy = decyear(i,j,15,k,0,0);
                  Output.hTOCMonthlyMean(l,:) = [dy i j k mTOC sTOC maxTOC minTOC length(dummy)];
              end
          end
      end
  end
and the moment the script terminates the array dummy is
>> dummy
dummy =
    368.8352
    334.5709
    341.9396
I would appreciate any help to resolve this issue

Put
clear min
just prior to the for-loop. Preferably also, avoid using "min" as the name of one of your variables.
