                 Summary: some function fail when DIM>=3 and size(X,DIM)==1

Details:

When DIM>=3 and size(X,DIM)==1, some functions work, such as "max", "min",
"sum", "prod",

>>  max(1:3, [], 3)
ans =

   1   2   3

>>  sum(1:3, 3)
ans =

   1   2   3



but some functions fail, such as "fft", "mean", "diff",

>>  fft(1:3, 256, 3)
error: fft: DIM must be a valid dimension along which to perform FFT
>>  fft(1:3, [], 3)
error: fft: DIM must be a valid dimension along which to perform FFT
>>  diff(1:3, [], 3)
error: DIM must be a valid dimension
>>  mean(1:3, 3)
error: mean: DIM must be an integer and a valid dimension
error: called from
    mean at line 110 column 7


I'm not sure whether this is a bug or a feature,

although sometimes this is inconvenient and we have to make a workaround by
"resize" or "postpad" X to make sure size(X,DIM)>=2 before calling these
functions.
