Hi Ed,
Was this the official announcement of PDL2.099?

u'd want to not do something on the whole ndarray,
but instead do something on a $pdl->where(condition...). What do you think?

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

Hi Ed,
yes I realize that problem and use r2C on $r before to apply

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)

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

Thanks Ed,
Using ternary conditional expression

Hi Guillermo,
You can do that indeed, that's just Perl. If you wanted to do operations on a
subset of that ndarray, then you'd do e.g.
$pdl->where(($pdl-0.5)->abs < 0.2) *= 5;
An observation is that the above condition could be a bit shorter by using the
recently-added approx_artol: (which wou
