[Octave-bug-tracker] [bug #52904] "mesh" with input array of "logical" causes error

[Markus Mützel]

Follow-up Comment #14, bug #52904 (project octave):

This is in Matlab R2016a:

>> h = line ([0 1], [0 1], 'createfcn', @() error ('fail to create'))
Error using @()error('fail to create')
Too many input arguments.
 
Error while evaluating Line CreateFcn


h = 

  Line with properties:

              Color: [0 0.4470 0.7410]
          LineStyle: '-'
          LineWidth: 0.5000
             Marker: 'none'
         MarkerSize: 6
    MarkerFaceColor: 'none'
              XData: [0 1]
              YData: [0 1]
              ZData: [1x0 double]

  Show all properties

>> ishghandle(h)

ans =

     1


The line is created even if the CreateFcn fails.

There seems to be another difference with respect to Octave. If I want the
error message to appear, the anonymous function has to be changed (note the
additional varargin):

>> h = line ([0 1], [0 1], 'createfcn', @(varargin) error ('fail to create'))
Error using @(varargin)error('fail to create')
fail to create
 
Error while evaluating Line CreateFcn


h = 

  Line with properties:

              Color: [0 0.4470 0.7410]
          LineStyle: '-'
          LineWidth: 0.5000
             Marker: 'none'
         MarkerSize: 6
    MarkerFaceColor: 'none'
              XData: [0 1]
              YData: [0 1]
              ZData: [1x0 double]

  Show all properties


But that is a different compatibility issue. With respect to this bug here,
both behave the same.
