MATLAB: Size gives contradictory results

lengthMATLABsize;vectors

Dear all,
I have a vector called "centers" which should be 1×26. When I call "whos centers" I obtain:
>> whos centers
Name         Size            Bytes  Class     Attributes
centers      1x26              208  double
Which makes sense. When I type "centers" the whole vector is displayed, and its size is 1×26. When I call "size(centers, 2)" I obtain 26, which also makes sense. However, when I call "size centers" I obtain:
>> size centers
 ans =
     1     7
Also, when I type "length centers" I obtain:
>> length centers
 ans =
     7
Does anybody understand what is happening here? I am quite puzzled.
Thank you very much,
Miguel

If you want the size of your vector you should use the following comment:
size(centers)
"size centers" shows the size of word "centers"! Also the same for the "length". size(centers, 2) returns the size of second dimension (26). size(centers, 1) returns the size of the first dimension (1).
