Needed to convert a one dimensional array to a two dimensional numpy matrix and then add a row vector to the end of the matrix.

import numpy array1d = range(10,100) array2d = [array1d[i:i + 10] for i in range(0, len(array1d), 10)] newline = [88 for i in range(1,11)] m = numpy.matrix(array2d) m_extended = numpy.vstack([m, newline])
