Hi, What is the best calculator/package for Laplace transforms in HP series? Thanks in advance.

Hi;

The ones that would help you right away are the HP49G+ and HP50G. Both offer Laplace transforms and their inverses as internal resources (should check OS and CAS version). If you want alternatives, there are some HP41 programs (a complete set, by Raymond D. Moore) that allow you to numerically evaluate Laplace transforms in expressions with up to seventh order polynomials .

Hope this helps.

I have matlab on my computer but it's slow at showing Laplace results.(4 core pc..) I wonder how much it takes for Hp50g.

Note: I'm an aerospace engineering student. I consider buying a used Hp50g (around 90$). Do you think it's worth this price?

Thanks for your help.

According to this document: http://www.casio-intl.com/calc/pdf/2008/08_all.pdf, the Classpad 330 does it!

Any examples of specific problems you're trying to do?

Also the 48 series with the addition of one of the Sparcom Mathematics Pacs cards. Then there's programs on HPCalc.org
