numpy.matlib.ones() is another function for doing matrix operations in numpy. It returns a matrix of 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 i.e. (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]]
