[Octave-patch-tracker] [patch #8801] add support for the histogram and histcounts functions

[Nicholas Jankowski]

Follow-up Comment #14, patch #8801 (project octave):

running through a few examples from the matlab help, i think at least Philip's
version is not quite compatible yet. (i'm not set up to compile octave to
test, so can't say whether the c version works) e.g.,:

Matlab doc:

X = [2 3 5 7 11 13 17 19 23 29];
[N,edges] = histcounts(X,6)
N = 1×6

     2     2     2     2     1     1

edges = 1×7

         0    4.9000    9.8000   14.7000   19.6000   24.5000   29.4000



Octave:

X = [2 3 5 7 11 13 17 19 23 29];
[N,edges] = histcounts(X,6)
N =

   3   1   2   2   1   1

edges =

 Columns 1 through 6:

    2.0000    6.5000   11.0000   15.5000   20.0000   24.5000

 Column 7:

   29.0000



Matlab docs:

X = primes(100);
[N,edges] = histcounts(X, 'Normalization', 'probability')
N = 1×4

    0.4000    0.2800    0.2800    0.0400

edges = 1×5

     0    30    60    90   120


Octave:

X = primes(100);
 [N,edges] = histcounts(X, 'Normalization', 'probability')
N =

   0.4400   0.2800   0.2800

edges =

    2.0000   33.6667   65.3333   97.0000
