[source]
Matrix of ones.
Return a matrix of given shape and type, filled with ones.
Parameters: |
shape : {sequence of ints, int} Shape of the matrix dtype : data-type, optional The desired data-type for the matrix, default is np.float64. order : {‘C’, ‘F’}, optional Whether to store matrix in C- or Fortran-contiguous order, default is ‘C’. |

Returns: |
out : matrix Matrix of ones of given shape, dtype, and order. |
