literal name; wronskian

Description

• 

The simplify/wronskian function is used to simplify expressions that contain the subexpression fg'gf', denoted wrf,g, with f and g special functions.  In particular, it recognizes the wronskians of

  

* Identical functions whose indices sum to zero, for example, wrJv,z,Jv,z

  

* Two functions with the same indices, for example, wrJv,z,Yv,z

  

* A function with arguments that sum to zero, for example, wrDv,z,Dv,z
