Hi,
I've been happily using where (for conditional plotting) since I was
pointed to it here some time ago. Now I've run into a problem.
This works for me:
points ($y->where($dsigma<10),$sigma->where($dsigma<10));
but this doesn't:
points ($y->where($dsigma<10 and $v>100),$sigma->where($dsigma<10 and $v>100));
The problem here is the 'and' operator - it does not work with
multi-element piddles. What you want is to use '&' instead:
$a=sequence(10)
print $a->where($a > 2 & $a < 7)
[3 4 5 6]
Also useful to know are 'any' and 'all'
J.
