Details:

Using the struct expansion feature of inputParser with a struct with no fields
as input produces an error instead of returning default values in Results. 

To reproduce the problem consider the following minimal example:


test = inputParser();
addParameter(test, 'param', 1)
parse(test, struct())


which produces the following error:


error: non-string for Parameter name or Switch
error: called from
    error at line 553 column 7
    parse at line 459 column 11
