Subject: [OctDev] Cell array (of structs) to array failure
To: octave-dev at lists.sf.net


I may be doing this completely wrong, but it works in some cases and
used to work reliably (in 3.0.5).

I've got a function returning a cell array of structs or empty
elements which I'm appending to form a single array of structs.
cors = [cors c{:}]
This used to work, and still does most of the time.

In fact, just [c{:}] is failing sometimes with the same error...
error: octave_base_value::complex_array_value(): wrong type argument `struct'

Any clue as to the problem, or suggestion how to do this sort of
append differently (or better)?

Sorry, I can't seem to duplicate the results with very simple
inputs... they all seem to work.
I'm attaching a saved variable "c" which fails.

Here is as trimmed down a version as I can get:
