numpy.matlib.empty() is another function for doing matrix operations in numpy.It returns a new matrix of given shape and type, without initializing entries.
Syntax : numpy.matlib.empty(shape, dtype=None, order=’C’)
Parameters :
shape : [int or tuple of int] Shape of the desired output empty matrix.
dtype : [optional] Desired output data-type.
order : Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory.Return : A new matrix of given shape and type,
Code #1 :
# Python program explaining # numpy.matlib.empty() function # importing numpy and matrix library import numpy as geek import numpy.matlib # desired output matrix out_mat = geek.matlib.empty((2, 3)) print ("Output matrix : ", out_mat) |
Output :
Output matrix : [[ 6.93621940e-310 2.43141878e-316 6.93621669e-310] [ 6.93621669e-310 6.93621553e-310 6.93621553e-310]]
Code #2 :
# Python program explaining # numpy.matlib.empty() function # importing numpy and matrix library import numpy as geek import numpy.matlib # desired output matrix out_mat = geek.matlib.empty((2, 3), dtype = int, order = 'C') print ("Output matrix : ", out_mat) |
Output :
Output matrix : [[140133380791224 140133380791224 140133356100528] [140133356100336 140133356100592 140133343343704]]
