Use python code to (a) make the 30 30-matrix A = [aij ] defined by the property aij = 0 if i j 1 if i < j, (b) compute A29 and A30. [Hint: your code could start with the two lines import numpy as np A = np.zeros((30,30), dtype=int) since this initiates A as a 30 30-matrix of integers with every set to zero. You then need to put the entry 1 into the places in A where it belongs and after that compute the stuitable power of the matrix. If you want to copy A into another variable B, use B=A.copy()]
