[Numpy-discussion] Relative speed

2013-08-29 Thread Anubhab Baksi
Hi, I need to know about the relative speed (i.e., which one is faster) of the followings: 1. list and numpy array, tuples and numpy array 2. list of tuples and numpy matrix (first one is rectangular) 3. random.randint() and numpy.random.random_integers() Thank you.

And as you pointed out, most of the time for non-trivial datasets the numpy operations will be faster. (I'm daunted by the notion of trying to do linear algebra on lists of tuples, assuming that's the relevant set of operations given the comparison to the matrix class.) Note the
