Hi Boyd,
thank you very much for your suggestions.
Using that idea we might obtain a simpler solution.

OK Ed,
in my version PDL2.098 still there does not exist whichND_both.
But, let me resume here the problem

Hi Ed,
yes, just I was trying with where_both
But I get unexpected behaviour for me in 2D case
1) first in 1D
pdl> $r=zeroes(3)->ndcoords/2-pdl(0.5)

Hello again,
I find some a not pretty solution using whereND

For instance, I am trying with $r, like below
$r=(zeroes(2*$N+1,2*$N+1)->ndcoords-pdl($N,$N))/(2*$N+1)

Hello !
I am not sure, but maybe It is possible to do with perl PDL something
like this?
$ndarray= condition on $ndarray ? assign when true : assign when false
for example:
$x=zeroes(20)->xlinvals(0,1);
$y=(all abs($x-0.5)<0.2)?$x**2:$x;
Thanks in advance
