shape : integer or sequence of integers order : C_contiguous or F_contiguous C-contiguous order in memory(last index varies the fastest) C order means that operating row-rise on the array will be slightly quicker FORTRAN-contiguous order in memory (first index varies the fastest). F order means that column-wise operations will be faster. dtype : [optional, float(byDeafult)] Data type of returned array.
ndarray of ones having given shape, order and datatype.
Matrix b : [1 1] Matrix a : [[1 1] [1 1]] Matrix c : [[ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.]]
Note : Ones, unlike zeros and empty, does not set the array values to zero or random values respectively.Also, these codes won’t run on online-ID. Please run them on your systems to explore the working.
