transpose python np array
numpy.matrix.transpose. Returns a view of the array with axes transposed. For a 1-D array, this has no effect. (To change between column and row vectors, first cast the 1-D array into a matrix object.) ,Same as self.transpose(), except that self is returned if self.ndim < 2. Examples. >>> >>> x = np.array([[1.,2.],[3.,4.]]) >>> x array([[ 1., 2.], [ 3., 4.]]) >>> x.T array([[ 1. ,numpy.ndarray.transpose. Returns a view of the array with axes transposed. For a 1-D array, this has no effect. (To change between column and row vectors, first cast the 1-D array into a matrix object.) ,Notes.
