Another way to vectorize operations is to use NumPy's broadcasting functionality: creating rules for applying binary ufuncs like addition, subtraction, or multiplication on arrays of different sizes.Earlier, when we performed binary operations on arrays of the same size, those operations were done on...
Plot of function evaluated on grid Expressing Conditional Logic as Array Operations The numpy.where function is a vectorized version of the ternary expression x if condition else y. Suppose we had a boolean array and two arrays of values: In [140]: xarr = np.array([1.1, 1.2, 1.3, 1.4,...
- If both `a` and `b` are 2-D arrays, it is matrix multiplication, but using :func:`matmul` or ``a @ b`` is preferred. - If either `a` or `b` is 0-D (scalar), it is equivalent to :func:`multiply` and using ``numpy.multiply(a, b)`` or ``a * b`` is prefe...
