numpy.multiply() in Python

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 :
arr1 : [array_like or scalar]1st Input array.
arr2 : [array_like or scalar]2nd Input array.
dtype : The type of the returned array. By default, the dtype of arr is used.
out : [ndarray, optional] A location into which the result is stored.
-> If provided, it must have a shape that the inputs broadcast to.
-> If not provided or None, a freshly-allocated array is returned.
where : [array_like, optional] Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
**kwargs : Allows to pass keyword variable length of argument to a function. Used when we want to handle named argument in a function.

Return : [ndarray or scalar] The product of arr1 and arr2, element-wise.

Code #1 :

 # Python program explaining # numpy.multiply() function    import numpy as geek in_num1 = 4 in_num2 = 6    print ("1st Input  number : ", in_num1) print ("2nd Input  number : ", in_num2)      out_num = geek.multiply(in_num1, in_num2)  print ("output number : ", out_num)

Output :

1st Input number :  4
2nd Input number :  6
output number :  24

Code #2 :

 # Python program explaining # numpy.multiply() function    import numpy as geek    in_arr1 = geek.array([[2, -7, 5], [-6, 2, 0]]) in_arr2 = geek.array([[0, -7, 8], [5, -2, 9]])     print ("1st Input array : ", in_arr1) print ("2nd Input array : ", in_arr2)          out_arr = geek.multiply(in_arr1, in_arr2)  print ("Resultant output array: ", out_arr)

Output :

1st Input array :  [[ 2 -7  5]
[-6  2  0]]
2nd Input array :  [[ 0 -7  8]
[ 5 -2  9]]
Resultant output array:  [[  0  49  40]
[-30  -4   0]]
