### Numerical calculation on sagemath: speed?

I mostly use Sagemath for performing symbolic operations on trigonometric polynomials. But I was wondering if it is also a good tool in numerical methods. This includes matrix operations and iterative solution of PDE's with finite difference methods. Usually I take the Sagemath outputs in another program more suited to numerical work. But I was wondering if Sagemath itself is a viable choice in this resepct. Can you tell me about its numerical performance and speed compared to other programs such as C, Matlab, Julia, Mathematica etc.? Thanks
