You are using the wrong shape for (1 1 1): it is a column vector, not a row one. import numpy as np A = np.array ( [ [1,2,3], [2,1,1]]) one_array = np.ones ( (3, 1)) A_inv = np.linalg.pinv (A) v = np.dot (A_inv, np.dot (A, one_array)) while if you define it as np.array ( [1, 1, 1]) the shape is (3,), i.e. a row vector.
