Dear all, I am looking for a way to use lists or arrays of values in equations in a similar way to Mathematica, Matlab or Fortran. A simple example would be:
sage: f = 2*x^3+1 sage: v = [1,2,3] sage: f(x=v) Traceback (click to the left for traceback) ... TypeError: cannot coerce type '<type 'list'>' into a SymbolicExpression. I would have liked something like [3,17,55] as a result. I tried something similar with vectors, matrices and numpy arrays, but I didn't manage to get the desired result. Is there an easy way of performing operations on arrays or lists without defining loops? Thanks for your help already!
