  • Last Updated : 20 Feb, 2019

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,
