[Octave-bug-tracker] [bug #60482] hist() misses error for non-numeric input

[Nicholas Jankowski]

Follow-up Comment #1, bug #60482 (project octave):

comparing for compatibility what happens with Matlab 2021a:


>> data =
'AABBBBBCCCCCCDDDDDDEFFFFFGGGHHHHHHHJJJJJJKKLLLLMMMMMMMMNNOOOPPPPPPPRRRSSSSSSSSTTUVVVWWWWWWWW'

data =

   
'AABBBBBCCCCCCDDDDDDEFFFFFGGGHHHHHHHJJJJJJKKLLLLMMMMMMMMNNOOOPPPPPPPRRRSSSSSSSSTTUVVVWWWWWWWW'

>> u = unique(data)

u =

    'ABCDEFGHJKLMNOPRSTUVW'

>> freq = hist (dada, u)
Unrecognized function or variable 'dada'.
 
Did you mean:
>> freq = hist (data, u)
Error using hist (line 75)
Input arguments must be numeric or a categorical array.
 
>> freq = hist (data + 0, u)
Error using hist (line 75)
Input arguments must be numeric or a categorical array.
 
>> freq = hist (data+0, u+0)

freq =

     2     5     6     6     1     5     3     7     6     2     4     8     2
    3     7     3     8     2     1     3     8
