Ideally you should be able to just do np.array(Matrix(...), dtype=float) (or dtype=int) to create a numpy array with a native dtype. But it looks like there is a bug that prevents it from working (https://github.com/sympy/sympy/issues/14943). So for now you can use
from sympy import matrix2numpy matrix2numpy(M, dtype=float) Aaron Meurer On Thu, Jul 19, 2018 at 1:25 AM, Math newbie <[email protected]> wrote: > Let's say I have a matrix M in the SymPy Matrix class, how may I create a > Numpy array variable that takes the same values as in M? > > I tried np.array(M).
