[Octave-bug-tracker] [bug #44659] Plotting the result of (==) comparison of two vectors does not plot properly

[Pantxo Diribarne]

Follow-up Comment #1, bug #44659 (project octave):

Hi,

Thanks for your bug report. You are using a pretty old version of Octave.
Since then things have changed: 3.8.1 triggers another error message 


error: invalid value for array property "ydata"
error: called from:
error:   /usr/share/octave/3.8.1/m/plot/draw/private/__stem__.m at line 135,
column 7
error:   /usr/share/octave/3.8.1/m/plot/draw/stem.m at line 127, column 8



4.0.0rc1 explicitly says that inputs should be numeric (not boolean as in your
example):


error: stem: X and Y must be numeric
error: called from
    __stem__>check_stem_arg at line 254 column 7
    __stem__ at line 37 column 40
    stem at line 127 column 8


Can you check how Matlab handles this example? Do they turn bool into double?
