[Octave-bug-tracker] [bug #42050] fplot does not work with anomynous function handle

[Mike Miller]

Follow-up Comment #5, bug #42050 (project octave):

I completely agree, the Matlab documentation makes it clear that the function
or function handle passed in to fplot must accept a vector and return a vector
of the same length which is the result of evaluating the function elementwise.
Therefore @(x)1/x is an invalid argument for fplot, undefined behavior
ensues.

What I would recommend (I haven't looked into fplot yet) is perhaps an error
if the size of the output obtained from calling the given function is not what
is expected. That could make the problem clearer than a generic "nonconformant
arguments" error.
