    Question about Perl "exp" function? Please help!

    Sorry I should've followed the "code" rules. Here is my code - thanks!!! sub func { my $x = shift; return (1/(sqrt($Vz*2*3.1416)+0.000001))*exp(-(($x-$Mz)**2)/((2*($Vz**2))+0.000001)); }

    Question about Perl "exp" function? Please help!

    In my Perl code I aim to compute the Gaussian integral, and the Gaussian function is expressed as ###code### sub func { my $x = shift; return (1/(sqrt($Vz*2*3.1416)+0.000001))*exp(-(($x-$Mz)**2)/((2*($Vz**2))+0.000001)); } ###code### , where I integral from 0 to 1, and $Vz is the...

    About using a function pointer/reference in Perl?

    I'm trying to use Eric Boesch's library, Math::Integral::Romberg, for the integral of a Gaussian distribution from 0 to 1. However I have some problems about "a reference to the function to be integrated". In my code, I wrote $area=integral(\&func, 0, 1); to do the integration, which is...
