try changing `end' with length(s). This question has already arised
here, `end' being the length of a vector. At the time I remember that
John Eaton asked if this was a valid Matlab construct, but nobody
answered. So I opened my win95 under sco-unix ;-), run my matlab 4.0,
and typed:


» a=1:10;
» a(1:end)

ans =

     []

» help end

 END    Terminates the scope of FOR, WHILE and IF statements.
        Without END's, FOR, WHILE, and IF wait for further input.
        Each END is paired with the closest previous unpaired
        FOR, WHILE, or IF and serves to terminate its scope. 

» version

ans =

4.0

» 

so it seems that `end' is not valid here (neither with a strings)but I
remember using it in matlab... when I use to use matlab.

Also, under octave,

 usage: reshape (a, m, n)

 Form an m x n matrix from the elements of a (taken in Fortran's
 column major ordering).
