Unlike `matrix`, `asmatrix` does not make a copy if the input is already a matrix or an ndarray. Equivalent to ``matrix(data, copy=False)``. Parameters ---------- data : array_like Input data. dtype : data-type Data-type of the output matrix. Returns ------- mat : matrix `data` interpreted as a matrix.

For positive integers `n`, the power is computed by repeated matrix squarings and matrix multiplications. If ``n == 0``, the identity matrix of the same shape as M is returned. If ``n < 0``, the inverse is computed and then raised to the ``abs(n)``. Parameters ---------- M : ndarray or matrix object Matrix to be "powered." Must be square, i.e. ``M.shape == (m, m)``, with `m` a positive integer. n : int The exponent can be any integer or long integer, positive, negative, or zero. Returns ------- M**n : ndarray or matrix object The return value is the same shape and type as `M`; if the exponent is positive or zero then the type of the elements is the same as those of `M`. If the exponent is negative the elements are floating-point. Raises ------ LinAlgError If the matrix is not numerically invertible. See Also -------- matrix Provides an equivalent function as the exponentiation operator (``**``, not ``^``). Examples -------- >>> from numpy import linalg as LA >>> i = np.array([[0, 1], [-1, 0]]) # matrix equiv. of the imaginary unit >>> LA.matrix_power(i, 3) # should = -i array([[ 0, -1], [ 1, 0]]) >>> LA.matrix_power(np.matrix(i), 3) # matrix arg returns matrix matrix([[ 0, -1], [ 1, 0]]) >>> LA.matrix_power(i, 0) array([[1, 0], [0, 1]]) >>> LA.matrix_power(i, -3) # should = 1/(-i) = i, but w/ f.p. elements array([[ 0., 1.], [-1., 0.]]) Somewhat more sophisticated example >>> q = np.zeros((4, 4)) >>> q[0:2, 0:2] = -i >>> q[2:4, 2:4] = i >>> q # one of the three quaternion units not equal to 1 array([[ 0., -1., 0., 0.], [ 1., 0., 0., 0.], [ 0., 0., 0., 1.], [ 0., 0., -1., 0.]]) >>> LA.matrix_power(q, 2) # = -np.eye(4) array([[-1., 0., 0., 0.], [ 0., -1., 0., 0.], [ 0., 0., -1., 0.], [ 0., 0., 0., -1.]]) � r r z input must be a square arrayzexponent must be an integer)�invN���� �0�1)r �ndim�shaper r �type�int� TypeErrorZ numpy.linalgr, r* r �range�N�dotr r ) �M�nr, �result�_�beta�Z�q�t�kr& r& r' � matrix_powerB s: G rB c @ sv e Zd ZdZdZdKdd�Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� Zdd � Zd d � Zd d � ZdLd!d"�ZdMd#d$�ZdNd&d'�ZdOd(d)�ZdPd+d,�ZdQd-d.�ZdRd/d0�ZdSd1d2�ZdTd3d4�ZdUd5d6�Z dVd7d8�Z dWd9d:�Z dXd;d<�Z dYd=d>�Z d?d@� Z!dAdB� Z"dCdD� Z#dZdEdF�Z$dGdH� Z%dIdJ� Z&e'e%d�Z(e'e"d�Z)e'e#d�Z*e'e&d�Z+e'e!d�Z,dS )[r a� matrix(data, dtype=None, copy=True) Returns a matrix from an array-like object, or from a string of data. A matrix is a specialized 2-D array that retains its 2-D nature through operations. It has certain special operators, such as ``*`` (matrix multiplication) and ``**`` (matrix power). Parameters ---------- data : array_like or string If `data` is a string, it is interpreted as a matrix with commas or spaces separating columns, and semicolons separating rows. dtype : data-type Data-type of the output matrix. copy : bool If `data` is already an `ndarray`, then this flag determines whether the data is copied (the default), or whether a view is constructed.

Parameters ---------- obj : str or array_like Input data. If a string, variables in the current scope may be referenced by name. ldict : dict, optional A dictionary that replaces local operands in current frame. Ignored if `obj` is not a string or `gdict` is `None`. gdict : dict, optional A dictionary that replaces global operands in current frame. Ignored if `obj` is not a string. Returns ------- out : matrix Returns a matrix object, which is a specialized 2-D array. See Also -------- block : A generalization of this function for N-d arrays, that returns normal ndarrays. Examples -------- >>> A = np.mat('1 1; 1 1') >>> B = np.mat('2 2; 2 2') >>> C = np.mat('3 4; 5 6') >>> D = np.mat('7 8; 9 0') All the following expressions construct the same block matrix: >>> np.bmat([[A, B], [C, D]]) matrix([[1, 1, 2, 2], [1, 1, 2, 2], [3, 4, 7, 8], [5, 6, 9, 0]]) >>> np.bmat(np.r_[np.c_[A, B], np.c_[C, D]]) matrix([[1, 1, 2, 2], [1, 1, 2, 2], [3, 4, 7, 8], [5, 6, 9, 0]]) >>> np.bmat('A,B; C,D') matrix([[1, 1, 2, 2], [1, 1, 2, 2], [3, 4, 7, 8], [5, 6, 9, 0]]) Nr- )ru r )rG rK �sys� _getframe�f_back� f_globals�f_localsr r� rW r` r7 rI r r )rY r� r� �frameZ glob_dictZloc_dictZarr_rowsr! r& r& r' r m s" 5 )N)NN)� __future__r r r �__all__r� r Znumpy.core.numeric�core�numericr7 r r r r r Znumpy.core.numerictypesr r( r rB rI r r� r r r& r& r& r' �<module> s( "l - M
