resize

[Francesco Potorti`]

What does the resize function do?

Its help string makes one think that it does the same as reshape, only
in place:
 -- Built-in Function:  resize (X, M, N)
     Destructively resize X.

     *Values in X are not preserved as they are with `reshape'.*

     If only M is supplied and it is a scalar, the dimension of the
     result is M-by-M.  If M is a vector, then the dimensions of the
     result are given by the elements of M.  If both M and N are
     scalars, then the dimensions of the result are M-by-N.

     See also: reshape.

However, it does not do that:

octave> resize((1:3*4)',[3 4])
ans =

   1   0   0   0
   2   0   0   0
   3   0   0   0

Is it a sort of truncation?
