In fact matlab accepts fractional month and I suppose we should too. I fixed this issue differently in the chanageset 4f458e882516

Apparently the reason is that the calculation of the separation between ticks can lead to fractional month value. I propose to add a test in datenum.m to throw a more explicit error in case month value is fractional and a slight correction to datetick to avoid fractional month values.

Confirmed at revision 14542:bf219932bf3e. Would you like to attempt to debug this yourself?

Some date ranges cause datetick to throw an error.

The following throws an error:


The error is:

error: datenum: subscript indices must be either positive integers or logicals
error: called from:
error:   /opt/local/share/octave/3.4.3/m/time/datenum.m at line 110, column 5
error:   /opt/local/share/octave/3.4.3/m/time/datetick.m at line 183, column 14
error:   /opt/local/share/octave/3.4.3/m/time/datetick.m at line 42, column 5

The following does not throw an error:
