Return a possibly reshaped matrix.

- axisNone or int or tuple of ints, optional
Selects a subset of the axes of length one in the shape. If an axis is selected with shape entry greater than one, an error is raised.
The matrix, but as a (1, N) matrix if it had shape (N, 1).
If m has a single column then that column is returned as the single row of a matrix. Otherwise m is returned. The returned matrix is always either m itself or a view into m. Supplying an axis keyword argument will not affect the returned matrix but it may cause an error to be raised.
>>> c = np.matrix([, ]) >>> c matrix([, ]) >>> c.squeeze() matrix([[1, 2]]) >>> r = c.T >>> r matrix([[1, 2]]) >>> r.squeeze() matrix([[1, 2]]) >>> m = np.matrix([[1, 2], [3, 4]]) >>> m.squeeze() matrix([[1, 2], [3, 4]])
