Details:

operators with a scalar.  And it implements the corresponding
element-by-elment operators for addition (.+) and subtraction (.-).  But it
does not implement element-by-elment multiplication.

For example:

octave:2> x = 1:5
x =

1   2   3   4   5

octave:3> typeinfo (x)
ans = range
octave:4> y = x * 2
y =

2    4    6    8   10

octave:5> typeinfo (y)
ans = range
octave:6> z = x .* 2
z =

2    4    6    8   10

octave:7> typeinfo (z)
ans = matrix
octave:2> x = 1:5
x =

1   2   3   4   5

octave:3> typeinfo (x)
ans = range
octave:4> y = x * 2
y =

2    4    6    8   10

octave:5> typeinfo (y)
ans = range
octave:6> z = x .* 2
z =

2    4    6    8   10

octave:7> typeinfo (z)
ans = matrix
octave:2> x = 1:5
x =

1   2   3   4   5

octave:3> typeinfo (x)
ans = range
octave:4> y = x * 2
y =

2    4    6    8   10

octave:5> typeinfo (y)
ans = range
octave:6> z = x .* 2
z =

2    4    6    8   10

octave:7> typeinfo (z)
ans = matrix
octave:2> x = 1:5
x =

1   2   3   4   5

octave:3> typeinfo (x)
ans = range
octave:4> y = x * 2
y =

2    4    6    8   10

octave:5> typeinfo (y)
ans = range
octave:6> z = x .* 2
z =

2    4    6    8   10

octave:7> typeinfo (z)
ans = matrix

This seems like an oversight and should be easy to fix as the
element-by-element operator should just map to the same routine that ordinary
multiplication is using.
