RE: problem with column specification in matrices

[Julian DeMarchi]

And on that note, Matlab yields

>> [ linspace (1, 2) ]
??? [ linspace (1, 2) ]
                 |
Error: ")" expected, "," found.

It does not like the space between function name linspace and argument list (1, 
2).

However,

  [n (1+1./n).^n]

and

  [n, (1+1./n).^n]

both yield identical results (space treated as comma).  Because, in Matlab (as 
in Octave),

>> n, (1+1./n).^n

n =

          10
         100
         500
        1000
        5000
       10000


ans =

    2.5937
    2.7048
    2.7156
    2.7169
    2.7180
    2.7181


So now I'm confused about what you mean about "indexing"...  If that was the 
reason it works in Matlab but not in Octave, why do they work the same way 
without brackets?

     Inside the square brackets that delimit a matrix expression, Octave
  looks at the surrounding context to determine whether spaces and newline
  characters should be converted into element and row separators, or
  simply ignored, so commands like

       [ linspace (1, 2) ]

  will work.  

IMHO, it was bad design for Matlab to make whitespace magic inside the
square brackets.
