Mean function not working on vector of doubles?

Hi all,

I have a vector of 1000 doubles (no NaNs at all) and I'm trying to find the mean of my vector but I'm only getting NaN returned? Can anyone help?

My data looks like:

      1.7694
      1.9135
      1.4977
      1.6484
      2.1447
      1.8067
      1.6340
      1.8504
      1.8398
      1.7225
      1.5068
      1.9008
      1.6895
      1.7423
      1.4253
      2.1948
      1.8581
      1.7909
      1.5839
      1.6750
      1.7101
      1.6638
      1.3526
      1.7562

(and on to 1000 similar estimators, all doubles, no NaNs, no complex numbers, nothing wonky)

And this is what happens:

betaMRmeanB = mean(data)

betaMRmeanB = NaN

Any help would be great.

Thanks!

to debug, could you try this and what is the output?

which -all mean
whos data

That may be what a small visible fraction looks like, but I'm betting it isn't what all the data "look like".

SHOW us, don't tell us...

all(isfinite(data))

returns???
