How to input function of Weber`s ?

[jjjjvb]

it`s Parabolic cylinder function - Wikipedia, the free encyclopedia

I need to input D of order (-0.5). Thanks

From your page

• I can get D(z) from U(a,z) and a from order -0.5, and get xi from a
• but U(a,z) requires y1, which requires F, but F = M which isn't on this page.

How far do we have to chase this and how much is it worth?

You need to do more work than you have before I'll do any more.  Let's see how much your Mathcad sheet has gotten!

I replaced function for http://dic.academic.ru/pictures/enc_mathematics/041703-49.jpg in attached file but the result which I got isn`t good

And where does it say that K is a Henkel function?

[jjjjvb]

The Mathcad 15 does not have emdedded function D, does it?

I added formula with function K but I don`t understand how to input  negative argument D in the formula replacing D?
