numpy.matlib.empty() function | Python

Last Updated : 22 Apr, 2020

numpy.matlib.empty() function return 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 empty matrix. dtype : [data-type, optional] Desired output data-type. order : [{‘C’, ‘F’}, optional] Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory. Return : [matrix] A new matrix of given shape and type, without initializing entries.

Code #1 :
