Update of bug #57726 (project octave):
Item Group: Other => Matlab Compatibility
Status: Wont Fix => Confirmed
Open/Closed: Closed => Open
Release: 5.1.0 => dev
Operating System: Microsoft Windows => Any
Summary: [octave forge] (symbolic) double not working on
symbolic expressions => [octave forge] (symbolic) dsolve should return
expression instead of equation
_______________________________________________________
Follow-up Comment #6:
Ok, I verified that the complete example does run in Matlab, thank you. If you
look closer, you can see that the main difference is the return value of
'dsolve'. In Matlab, 'dsolve' returns an expression, but Octave 'dsolve'
returns an equality.
If you run 'rhs' on the return value of Octave 'dsolve', you get the same
answer as Matlab.
So the compatibility bug here is that 'dsolve' should not return an equality
like "y(t) == expr", it should just return "expr". Does that look right to
you?
Reopening and changing the summary.
