numpy.matlib.ones¶

numpy.matlib.ones(shape,dtype=None,order='C')[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.

ones

Array of ones.

matlib.zeros

Zero matrix.

Notes

Ifshape has length one i.e.(N,), or is a scalarN,out becomes a single row matrix of shape(1,N).

Examples

>>>np.matlib.ones((2,3))matrix([[ 1.,  1.,  1.],        [ 1.,  1.,  1.]])

>>>np.matlib.ones(2)matrix([[ 1.,  1.]])
