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’)
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:
Output matrix: Output matrix: [[1. 1. 1. 1.] [1. 1. 1. 1.] [1. 1. 1. 1.]]
Code # 2:
Output matrix: [[1 1 1 1 1]]
