Re: Spurious `undefined' values and conversion issues

On line 1158:

my $split1 = (($energy_before[$j]-$energy_rebin[$k])*$totcount)/($ener
+gy_before[$j]-$energy_before[${j}-1]);
[download]

Note the "$energy_before[${j}-1]". What happens to that index when $j is 0?

Thanks for your suggestion, oko1. If $j=0, the if loop shouldn't run, as the logic condition given in the if statement is `if(($energy_rebin[$k] < $energy_before[$j]) && $j!=0){`. The problem for this case was that $j was too large due to a typograhical error in the 'for' loop and this yielded the undefined value problem. However, many thanks for looking through the code and for your suggestion. Steve	[reply] [d/l]
