speed of python vs matlab.

I've been trying to develop some numerical codes with python, however got disappointed. A very simple test, a = 1.0 for i in range(1000): for j in range(1000): a = a+1 unfortunately, it took 4.5 seconds to finish(my machines is fine. P4 3.0G, 1G RAM, it varies according to machi

s actually comparison between numpy(which is implemented in c) vs matlab. Chao. import psyco #psyco.bind(functest) psyco.full() import numpy import time,math def functest(a): array = xrange(1000) for i in array: for j in array: a = a + 1 tic = time.time() a = 1.0

HI, everybody. When I try to use numpy to deal with my dataset in the style of csv, I face a little problem. In my dataset of the csv file, some columns are string that can not convert to float easily. Some of them can ignore, but other columns I need to change the data to a enum st
