This numpy method returns an array of given shape and type as given array, with zeros.
Syntax: numpy.zeros_like(array, dtype = None, order = 'K', subok = True)
Parameters :
array : array_like input subok : [optional, boolean]If true, then newly created array will be sub-class of array; otherwise, a base-class array order : C_contiguous or F_contiguous C-contiguous order in memory(last index varies the fastest) C order means that operating row-rise on the array will be slightly quicker FORTRAN-contiguous order in memory (first index varies the fastest). F order means that column-wise operations will be faster. dtype : [optional, float(byDefault)] Data type of returned array.
Returns :
ndarray of zeros having given shape, order and datatype.
Code 1 :
Python
# Python Programming illustrating # numpy.zeros_like method import numpy as geek
array = geek.arange( 10 ).reshape( 5 , 2 )
print ( "Original array : \n" , array)
b = geek.zeros_like(array, float )
print ( "\nMatrix b : \n" , b)
array = geek.arange( 8 )
c = geek.zeros_like(array)
print ( "\nMatrix c : \n" , c)
|
Output:
Original array : [[0 1] [2 3] [4 5] [6 7] [8 9]] Matrix b : [[ 0. 0.] [ 0. 0.] [ 0. 0.] [ 0. 0.] [ 0. 0.]] Matrix c : [0 0 0 0 0 0 0 0]
Code 2 :
Python
# Python Programming illustrating # numpy.zeros_like method import numpy as geek
array = geek.arange( 10 ).reshape( 5 , 2 )
print ( "Original array : \n" , array)
array = geek.arange( 4 ).reshape( 2 , 2 )
c = geek.zeros_like(array, dtype = 'float' )
print ( "\nMatrix : \n" , c)
array = geek.arange( 8 )
c = geek.zeros_like(array, dtype = 'float' , order = 'C' )
print ( "\nMatrix : \n" , c)

Output :
Original array : [[0 1] [2 3] [4 5] [6 7] [8 9]] Matrix : [[ 0. 0.] [ 0. 0.]] Matrix : [ 0. 0. 0. 0. 0. 0. 0. 0.]
