| Returns: | out : ndarray The result of repeating a. |
Examples
import numpy.matlib a0 = np.array(1) np.matlib.repmat(a0, 2, 3) array([[1, 1, 1], [1, 1, 1]])
a1 = np.arange(4) np.matlib.repmat(a1, 2, 2) array([[0, 1, 2, 3, 0, 1, 2, 3], [0, 1, 2, 3, 0, 1, 2, 3]])
a2 = np.asmatrix(np.arange(6).reshape(2, 3)) np.matlib.repmat(a2, 2, 3) matrix([[0, 1, 2, 0, 1, 2, 0, 1, 2], [3, 4, 5, 3, 4, 5, 3, 4, 5], [0, 1, 2, 0, 1, 2, 0, 1, 2], [3, 4, 5, 3, 4, 5, 3, 4, 5]])
