When you try to transpose a 1D array, it does nothing.  This is the
correct behavior, since it transposing a 1D array is meaningless.
However, this can often lead to unexpected errors since this is rarely
what you want.  You can convert the array to 2D, using `np.atleast_2d`
or `arr[None]`, but this makes simple linear algebra computations more
difficult.

I propose adding an argument to transpose, perhaps called `expand` or
`expanddim`, which if `True` (it is `False` by default) will force the
array to be at least 2D.  A shortcut property, `ndarray.T2`, would be
the same as `ndarray.transpose(True)`.



Use `dot`.  E.g.,
        m.dot(a)
