numpy.matlib.empty()

This function is used to return a new matrix with the uninitialized entries.

Syntax

Parameters

It accepts the following parameters.

shape: It is the Tuple defining the shape of the matrix.
dtype: It is the data type of the matrix.
order: It is the insertion order of the matrix.

Return

A matrix with uninitialized entries is returned.

Example

import numpy as np  
  
import numpy.matlib  
  
print(numpy.matlib.empty((3,3)))  

Output:

[[6.94892251e-310 2.29200848e-316 0.00000000e+000]
 [0.00000000e+000 2.37151510e-322 2.37151510e-322]
 [0.00000000e+000 6.94889962e-310 0.00000000e+000]]

Example: initializing integer values

import numpy as np  
  
import numpy.matlib  
  
print(numpy.matlib.empty((3,3),int))  

Output:

[[140584865515528        35760528               0]
 [              0               0               0]
 [              0               0              0]]

Example: specifying Insertion order

import numpy as np  
  
import numpy.matlib  
  
print(numpy.matlib.empty((3,3),int,'C'))  

Output:

[[140437489977352        22202768               0]
 [              0               0               0]
 [              0               0              0]]
