Universal Functions (ufunc)

Mars tensor provides universal functions(a.k.a ufuncs) to support various elementwise operations. Mars tensor's ufunc supports following features of Numpy's one:

  • Broadcasting
  • Output type determination
  • Casting rules

Mars tensor's ufunc currently does not support methods like reduce, accumulate, reduceat, outer, and at.
