Verified fix with both original example and my simpler one. Marking as Fixed and closing report.

Confirmed. Octave is missing a conversion template.

A simpler method to reproduce is

The corresponding method of assigning assigning to doubles works

The error message is quite specific and quite accurate. It is the conversion of a double scalar to an indexed 'float complex scalar' that is missing. The conversion to a 'float matrix' exists and works correctly.

Strange. I have a really recent development version and see a problem here, but it manifests a little differently:

It looks like my median() comes from the nan package:

Where is your median originating from? I don't think there is a line #93 in my version.

Your guess does make sense in a way, i.e., that there is some missing C++ conversion whose definition was overlooked. But check where median is coming from and if it is an external file, check what line 93 is.

I ran into this error - not really sure what it means. Maybe a missing template somewhere deep in the C++ ...
