Datenum Problem in Octave???

I have an Problem with implementing a Matlab Code into Octave. i have an dt = char of the size 5x21

.
dt =
yearmonthdayt [hh:mm]
2016Jan  01 00:00
2016Jan  01 00:15
2016Jan  01 00:30
2016Jan  01 00:45

>> and use

datenum( dt, 'yyyymmmddHH:MM' );

but i get the following error message in Octave:

error: datevec: DATE not parsed correctly with given Format

error: called from datevec at line 147 column 11 datenum at line 104 column 40

@FishermanJack: if you have Octave problems then you should ask on an Octave forum.

Sadly, there isn't such a forum for Octave (or none that I can find). I would suspect this wouldn't run correctly in Matlab either, as that first line doesn't fit the format.

[FishermanJack]

as Rik said, neither i know a Forum for Octave, because of that i think i could ask someone here. if the question is not suitable for this Forum i will delete it.

Octave isn't Matlab despite it being similar and mostly syntax-similar.

While is OT here, from the error message I'd guess the problem is the format string isn't correct case for the month/hour/day fields...there's a difference between the old datenum and the new(er) datetime in who's upper- and who's lower- case; check the doc for "who's who in the zoo"...

The first entry is not parseable. The second others might have problems because of the spaces.

Answer 1

The first line 'yearmonthdayt [hh:mm]' cannot be parsed correctly. Try this:

datenum(cellstr(dt(2:end, :), 'yyyymmmddHH:MM')

Or do you have to consider the spaces?

datenum(cellstr(dt(2:end, :), 'yyyymmm  dd HH:MM')

The first suggestion worked fine, but the main reason was that i had to download the latest version of Octave.
