WebIs there a method included with numpy that could be used to do most of the heavy lifting? For example, this problem reduces to simultaneously diagonalizing real (U) and imag (U). As a wild guess I tested if the svd of real (U) + random.random ()*imag (U) would give a result that happened to work. WebThe following methods of Numpy arrays are supported: argsort () ( kind key word argument supported for values 'quicksort' and 'mergesort') astype () (only the 1-argument form) copy () (without arguments) dot () (only the 1-argument form) flatten () (no order argument; ‘C’ order only) item () (without arguments) itemset () (only the 1-argument form)
