hi guys,
i try to read cell excel :
[ a, b, c] = xlsread (percorsoNomeFile,1,'A2:A7');
there is 6 boxes excel
it read from excel:
A2="xxx";
A3="xxx";
A4="xxx";
A5=empty;
A6="xxx";
A7="empty";
now i print it:
c=
[1,1] = xxx
[2,1] = xxx
[3,1] = xxx
[4,1] = " "
[5,1] =xxx
there is n. 5 element not 6
how can i avoid to delete 1 element?
(i would like to read n.6 element ..no 5)
thank

Octave's xlsread strips empty outer columns and rows by default. In return
it gives a fourth (or fifth) output ("limits" below) that tells you from
which part of the sheet your numeric and textual data came from.
If you don't want that you'd have to specify an option, see "help xlsread"
and "help xls2oct" (admittedly it's a bit of searching in the long help
texts).
Something along the lines of:
[num, txt, raw, limits] = xlsread (<Excel file name>, <sheet name>, <range>,
<interface>, options)
In your case I suppose the following should work:
opts = struct ("strip_array", 0); ## Value is a numeric zero, or "false"
[ a, b, c] = xlsread (percorsoNomeFile, 1, 'A2:A7', '', opts);
Note the empty string between range and options.
Maybe this can be set as an alias in your .octaverc; I never tried.
Please report back if the above solves your problem.

I just tried this in Ubutu 18.10 and octave rc2 and io2.4.12
[ a, b, c] = xlsread ("calcfile.ods",1,'A2:A7') Detected XLS interfaces: a =
2 3 4 NaN 6 7
b = {}(0x0) c = { [1,1] = 2 [2,1] = 3 [3,1] = 4 [4,1] = [](0x0) [5,1] = 6 [6,1] = 7 }

turbofib writes "empty" where he apparently refers to an empty spreadsheet
cell (with nothing inside) where your outer cells (top and bottom of the
range) seem to contain contain the numbers 2 and 7, resp.
Plus you didn't specify the 5th options argument.
