Details:

csv2cell seems to handle space after the number, between number and separator
incorrectly.

Save the next 2 lines as file space.csv:


a,       b,   c
str_a, 3.0 , 18


read space.csv with the following script:


pkg load io;
ver = version
hg_id = __octave_config_info__.hg_id
pkg list io
data = csv2cell('space.csv', ',');
cellfun(@isnumeric, data)


The output is this (18 recognized as numeric, 3.0 not).
If I remove the space between 3.0 and "," 3.0 is recognized as a number.


ver = 5.1.1
hg_id = e07ea25d58f5+
