matrix operations | one () function

numpy.matlib.ones() — another function to do matrix operations in numpy. Returns a matrix of the given shape and type, filled with ones.

Syntax: numpy.matlib.ones (shape, dtype = None, order = ’C’)

Parameters:
shape: [int, int] Number of rows and columns in the output matrix.If shape has length one ie (N, ), or is a scalar N, out becomes a single row matrix of shape (1, N).
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: Matrix of ones of given shape, dtype, and order.

Code # 1:

# Python program explaining # numpy.matlib.ones () function    # import matrix library from numpy import numpy as geek import numpy.matlib   # desired 3 x 4 output matrix out_mat = geek.matlib.ones (( 3 , 4 ))  print ( "Output matrix:" , out_mat)

Output:

 Output matrix: Output matrix: [[1. 1. 1. 1.] [1. 1. 1. 1.] [1. 1. 1. 1.]] 

Code # 2:

# Python program explaining # numpy.matlib.ones () function   # import numpy library and matrix import numpy as geek import numpy.matlib   # desired 1 x 5 output matrix out_mat = geek.matlib.ones (shape = 5 , dtype = int )  print ( "Output ma trix: " , out_mat)

Output:

 Output matrix: [[1 1 1 1 1]]
