[Numpy-discussion] Is it possible with numpy?

There is a (small) chance that sympy can help. Never the less you can use scipy.optimize to obtain a numerical solution, once you specify the right merit function.

Hello Numpy community,
I want to know if Numpy could deal with symbolic arrays and lists (by
symbolic I mean without specifying the concrete contents of list or
array)
For example I want to solve a system of equations containing lists and
arrays like this
solve(x+Sum[A[k],k=i..N]==y+Sum[B[k],k=m..N], 
j-Length[C]==l-Length[D], 
 z/(c ^ i)==t/(c ^ h), 
u+1==2*v-3w, 
v=f(f(w))) 
(here A and B are arrays; C et D are lists; 
x,y,z,t,j,l,i,h,u,v,w are variables that could be of type integer or real, c is a constant and f is a function): 
 
Thank you very much.
Yours faithfully,

Olfa MRAIHI
