Function rand

numpy/matlib.py:233–277

Return a matrix of random values with given shape. Create a matrix of the given shape and propagate it with random samples from a uniform distribution over ``[0, 1)``. Parameters ---------- \\*args : Arguments Shape of the output. If given as N integers, ea

(*args)

    return asmatrix(np.eye(n, M=M, k=k, dtype=dtype, order=order))

    Return a matrix of random values with given shape.

    Create a matrix of the given shape and propagate it with
    random samples from a uniform distribution over ``[0, 1)``.

    Parameters
    ----------
    \\*args : Arguments
        Shape of the output.
        If given as N integers, each integer specifies the size of one
        dimension.
        If given as a tuple, this tuple gives the complete shape.

    Returns
    -------
    out : ndarray
        The matrix of random values with shape given by `\\*args`.
