Is it possible to store an NSMutableArray together with all its contents into a file and restore it later from there? Some kind of serialization available in iPhone OS? Is that practically possible or should I quickly forget about that? I am making a tiny app that stores some inputs in ...
array([3,2,0,1]) row = np.arange(4) # Display original data print("Original data:\n",arr,"\n") # Permutation p = np.zeros((4,4),dtype=int) p[row,arr] = 1 # Inverse of permutation res = np.where(p.T)[1] # Display permutation print("Permutation:\n",p,"\n") # ...
Accessing an Array Variable From One Function in Another Function Within the Same Class I have three functions within one class. The function listUpdates() is supposed to return $this->authors; How can I access this value in another function within the same class? I'm attempting to ac.....
Array permutation method [[1], [2], [3]] [[1, 2], [1, 3], [2, 1], [2, 3], [3, 1], [3, 2]] [[1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]] Explanation In the above code, you can observe that this method is used ...
