WebMay 16, 2024 · numpy.multiply () function is used when we want to compute the multiplication of two array. It returns the product of arr1 and arr2, element-wise. Syntax : numpy.multiply (arr1, arr2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True [, signature, extobj], ufunc ‘multiply’) Parameters : WebBasic operations on numpy arrays (addition, etc.) are elementwise This works on arrays of the same size. Nevertheless, It’s also possible to do operations on arrays of different sizes if NumPy can transform these arrays so that they all have the same size: this conversion is called broadcasting. The image below gives an example of broadcasting:
