Just a quick note to record that this issue also affects the stk package. Here is an example

Confirmed, the error is reported in octave_base_value::numeric_assign because Octave fails to treat a class with a `double` method as a known numeric conversion.

This is similar to https://savannah.gnu.org/bugs/?43097 (and is mentioned there). But the issue mentioned in the summary there is indeed closed.

Suppose you have a double array y.

Suppose you have an object x.

Try to assign "y(1) = x". This probably should call "double(x)" automatically (Matlab doeS). Instead we get an error.

Example using the Symbolic pkg:

This is downstream issue https://github.com/cbm755/octsympy/issues/191
