Less is always present on cygwin as it is a dependency
of some base packages.

If less is not present the message will be:

octave:1> source prova.m
/bin/sh: less: command not found

It is an issue with the installed "less".
Please install also libncursesw10-5.7-18

For cygwin mailing list:

less record on setup.ini is reporting:
"requires: cygwin libncurses10 libgcc1"

but less depends on libncursesw10

I don't know if Cygwin expects you to install a pager separately. Is one installed? I don't know why the Octave package seems to not be using this correctly.

I am CCing this bug report to the Cygwin list.

You are good.  I can't see ones(100,1) either.  If I set "more off" then all is well, except for lack of paging.  Inserting "more off" into my program works too.  I am using the build that I downloaded via the Cygwin setup.exe utility.  Thanks for your help.

I suspect a problem with the pager. What happens if you do





Do either of those give you an output?

Also, which 3.4.2 Windows build are you using, where did you acquire it, or did you build it yourself?

If I put the following code in an m-file, start Octave, and run the code:

clear all

the matrix v is not displayed.  If I try to use disp to view v I see nothing.  Typing whos shows the size of v is correct. It seems v has been computed correctly, but I can't see the entire result. I can view parts of v using the colon operator, for example a single row. If I change to an 8 by 3 size for u, then I see the result, i.e. it only seems to fail for larger matrices.  Similar behavior occurs after using rand.  If I replace the rand line with repmat to create u, then v is viewable.

GNU Octave, version 3.4.2
