[Scilab-users] New to Scilab and having issue with function I've written

[Klaus Rohe]

Hi,

the following function works fine (Scilab 5.5.1):

-->function [x]=isprime(num)
-->    vect=factor(num);
-->    if length(vect) == 1 then
-->        x=1;
-->    else
-->        x=0;
-->    end
-->endfunction
 
-->isprime(37)
 ans  =
 
    1.  
 
-->isprime(36)
 ans  =
 
    0.  

Kind regards

Klaus

Hey Robin:

I just tried this, and I'm not getting that behavior.  In over a decade of
using Scilab, I haven't seen that behavior.  So I'm not good for much help.

Two things that you can try, however, are:

1: If you haven't yet, try it again, in case the Evil Computer Gods have
been messing with your head.  Maybe close Scilab and open it again.

2: Tell us what Scilab version you're using, as well as what OS.  For your
Scilab version, type getversion (e.g. mine is Scilab-5.5.1).  This won't
help me help you, but it may help someone smarter than me help you.
