According to a test done on the maintainers mailing list, in Matlab 2017a:

>> [struct(), {}]

ans =

  struct with no fields.

When a struct is the leading element in a row vector concatenation, and the remaining elements are all empty cell arrays, they should be ignored, the same as if they were empty matrices.

For example, this works in Octave:

>> [struct(), [], [], []]
ans =

  scalar structure containing the fields:

If the trailing values are empty cell arrays, they should collapse the same way and the result should be just the scalar struct or struct array.
