Details:

This is legal in Matlab R2011b

>> [{}, struct()]

ans = 

    [1x1 struct]

but not in Octave:

octave:1> [{}, struct()]
error: octave_base_value::cell_value(): wrong type argument 'scalar struct'

Octave is consistent for other scalar or array types:

octave:2> [{}, 1]
ans =
{
  [1,1] =  1
}
octave:3> [{}, [1, 2]]
ans =
{
  [1,1] =

     1   2

}

A workaround is to enclose the scalar struct in parentheses:

octave:1> [{}, {struct()}]
ans =
{
  [1,1] =

    scalar structure containing the fields:


}
