Re: Re: Calculate Angle Between Three 3D Points

Thanks for the advice (and the rapid response!)
However, I cannot get Math::VectorReal to work with my Perl.
It gives the error message: Can't locate Math/VectorReal.pm in @INC

I think it would be easier for now to fix the code written
above, so does anyone see a mistake and know how to fix it?

That's because you have to install it from CPAN. It's not a module that comes standard with Perl. Click on the link: Math::VectorReal and download it. ------ We are the carpenters and bricklayers of the Information Age.
