Méthode numpy.matlib.matrix.squeeze

Signature de la méthode squeeze

def squeeze(self, axis=None) 

Description

help(matrix.squeeze)

Return a possibly reshaped matrix.

Refer to `numpy.squeeze` for more documentation.

Parameters
----------
axis : None 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.

Returns
-------
squeezed : matrix
    The matrix, but as a (1, N) matrix if it had shape (N, 1).

See Also
--------
numpy.squeeze : related function

Notes
-----
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.

Examples
--------
>>> c = np.matrix([[1], [2]])
>>> c
matrix([[1],
        [2]])
>>> 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]])
