Problem with the commands

[Cheung]

Hi,

I type the following commands to get the max of a and the index of that max.  My expected answer is: 

val = 15

ind = 2

But after I typed the following commands, I got an error message.  Could you please let me know how to write the commands correctly?

Thank you. 

Here are the commands I typed in Octave: 

>> a
a =

    1.00000   15.00000    2.00000    0.50000

>> [val. ind] = max (a)
parse error:

  syntax error

>>> [val. ind] = max (a)
          ^
