15.9 Parabolic Cylinder Functions ================================= The Parabolic Cylinder Functions are defined in Abramowitz and Stegun, Handbook of Mathematical Functions, Chapter 19. Maxima has very limited knowledge of these functions. They can be returned from function 'hgfred'. -- Function: parabolic_cylinder_d (<v>, <z>) The parabolic cylinder function 'parabolic_cylinder_d(v,z)'. (A&S 19.3.1)
