Follow-up Comment #1:

This sounds like you have NA or NaN in the data.  The function max and min
discard NA.  The function mean cannot do so.  As an example,


octave:2> x = [1 NA 3];
octave:3> min (x)
ans =  1
octave:4> max (x)
ans =  3
octave:5> mean (x)
ans = NA
octave:6> isna (x)
ans =

  0  1  0


What does this check for NA values in t1 return?


any (isna (t1(:)))
