A few personal routines to aid in symbolic computations.

Example to re-express product of two Gaussians as one:

#+BEGIN_SRC julia :session t :results output :exports both

  using SymPy

  using MySymPy

  @syms x N a b c d

  ex = N^2*exp(-a*x^2 + c)*exp(-b*x^2 + d)

  println()

  walk_expression(powsimp(ex)) do eee

      trans_gaussian(eee, x)

  end

#+END_SRC

#+RESULTS:

#+begin_example

(x,N,a,b,c,d)

         2           2    

 2  - a⋅x  + c  - b⋅x  + d

N ⋅ℯ          ⋅ℯ

             2        

 2  c + d - x ⋅(a + b)

N ⋅ℯ
